Who are you and what do you do?
Chris Angove is represented to clients by Faraday Consultancy Limited (FCL),
which was formed in 1994, and is also owned and managed by Chris Angove (telephone
+44 (0) 20 8249 0957 or +44 (0) 7989-305995). The company is registered in England
and Wales (registration number 2938426) and is registered for
Value Added Tax (VAT registration number GB 623 4028 72). FCL provides high calibre professional
engineering support to client companies across many electronics disciplines
including RF and microwave design and development,
broadcast and communications engineering, telecommunications, radar and defence systems engineering. FCL has supported clients' projects for both commercial and defence
equipment at many levels from hands-on circuit design through to major systems
implementation. If required, Chris either already has, or is qualified to get, security clearance
from the appropriate authorities.
How can you help my project/company?
In today's competitive environment, project managers are faced with challenging project milestones.
Promises made to the customer must be met. Personal
commitments, the company's reputation and ultimately peoples' jobs are at risk. FCL can help strengthen
such teams at short notice and make these goals realistically achievable. FCL has
already supported many clients like these and has successfully achieved similar objectives. FCL can bring a set of core skills built up over many years working in
similar industries. Just as important, FCL's representative, Chris Angove, is a very approachable engineer and enjoys
working with his peers in these environments.
Which Clients/Companies have you supported in the past?
FCL has supported the following clients:
Tell me about this guy Chris Angove?
Motorola (GSM Products Division), Arqiva (Terrestrial Media Solutions), ERA Technology,
Thales (Land and Joint Systems), Safran Power, Plextek, C-MAC Micro Technology,
Cubic Transportation Systems, Cable and Wireless, Marconi Radar Systems, Astrium Systems, Marconi Space and Defence Systems, Thorn EMI Electronics, Marconi Communication Systems, Nokia Telecommunications, GEC Marconi Communications, Redifon-MEL, GEC Marconi Electro-Optics,
Avanti Communications, Allen Vanguard UK, ITT Defence, Thales Defence (Airborne Systems), Alcatel Submarine Networks, Raytheon Systems, BAE Systems, EADS-Astrium.
Chris has had a passion for all aspects of electrical and electronics engineering from
his childhood. He was brought up in Cornwall and went to The Humphry Davy Grammar School
after which he completed a telecommunications course with Cable and Wireless
followed by secondment
for 2 years to the Emirates Telecommunications Corporation at the Dubai Satellite Ground Station, United Arab Emirates. There he was on the
24-hour duty engineering team and performed regular maintenance and installation duties on
the live international telecommunications equipment. The
hardware included C-band cooled microwave
low noise amplifiers, satellite receivers, modulators, upconverters, high power
amplifiers , uninterruptable power supplies, control/monitoring hardware and the antenna tracking equipment. His
maintenance of the station right down to the
three phase solid-state inverters, diesel generator sets, air-conditioning plants, ambient temperature
and humidity recording. He also supported the
maintenance at the nearby terrestrial site, whose services included VHF terrestrial, tropospheric scatter, microwave line-of-sight
and cable terminal equipment.
During the quiet periods on night duty he chose to study and
to further advance his understanding
of electrical engineering and communications.
When he returned to the UK he left Cable and Wireless and joined Marconi Space and Defence
Systems (MSDS) as a sponsored student on an honours degree (thin sandwich) course in Electrical and Electronics Engineering. He specialised in space hardware development at C and Ku bands and completed his honours degree
with an upper second. After a few years at MSDS he moved to Thorn EMI Electronics where he
joined the radiation laboratory and worked on the design and development of
various millimetre wave components, at the same time successfully completing an MSc in Microwaves and Modern
at University College London. Over the next few years he held various senior
engineering positions with several leading corporates. Because of his
broad experience he decided to market himself independently as a freelance
professional engineer in 1994. Since then he has supported many clients in a number of roles from strengthening existing project teams specifically
targeting and solving known design
and production issues.
Can I have a copy of Chris's CV?
Certainly. Please contact Chris directly. His mobile on +44 (0) 7989 305995
would be easiest. He will delighted
to send you one and to explain how he believes he (represented by FCL) can help you. To elaborate
on his skills and answer any questions you may have, he will be very pleased to meet you face to face at a time and place convenient to you.
Evidence of all the qualifications shown on the CV can of course be
Why should I use your services instead of those from company X?
Every contract has been a success: objectives met and
exceeded, specifications met and exceeded, documentation delivered and a comprehensive set of engineering records
and documents left with the client.
All contracts to date have started at either 3 months or more and many were
But eventually of course all contracts have to end and Chris is delighted to have worked with all clients and has made many friends. RF
and microwave engineering is a relatively small sector in the
UK so names and reputations are remembered. In the case of FCL they are remembered for their
hard work, reliability, high calibre and the consistently high level of professionalism delivered throughout the duration of the contract. FCL is also delighted to have supported
several clients on more than one occasion, having been invited back to work on new projects, sometimes even to the same team as previously.

FCL strictly follows the day to day notes recording and documentation requirements of the client. Usually the engineer will keep a registered engineering log book in which are detailed notes on the day to day work: equipment setups and serial numbers; contact details of suppliers, sources of information (references to websites,
equations etc.); test results summaries and calculations. These will be left with the client
when FCL's engineer leaves. FCL's policy on note keeping is to record
sufficiently detailed notes in such a way that tests, investigations etc. can be repeated
reliably at a later date
after FCL has left. FCL has received many positive comments about the
detail and high quality of both its routine note keeping and the formal reports
that it has produced.
FCL regards the production of quality documentation a critical part of all contracts. FCL's documents are relevant, concise, free from waffle,
repetition and unnecessary
words. Perhaps with the exception of Ohm's Law, no formula is stated without
references to reputable text books and/or recognised papers. High skill levels of the common
word processing, spreadsheet and graphics applications
are maintained to generate these. Quite often a client's milestone payments are conditional upon
the delivery of well written and correctly configured documents, acceptable to the customer. FCL has experience in writing most types of deliverable specifications
(requirements, design proving, test, acceptance) for many types of equipment. It
is also skilled in writing in the styles normally required for
application notes and user manuals.
How can we be sure that we will retain the skills and
knowledge gained whilst you are with us?
The client will benefit both from the skills that FCL has built up over
years working in similar industries and from the privately funded R&D work FCL
engages in to prepare for future contracts. Furthermore, unless the client requires otherwise, FCL will leave a set of very comprehensive documents with the client. On most contracts one of the client's senior engineers
or project managers works directly with FCL's representative to ensure that the best possible support is given. Quite often FCL's support covers a period whilst the client is searching to fill a
permanent staff position covering similar responsibilities. Once the new employee is found, FCL can work with him/her to ensure everything required is transferred, hardware demonstrated, questioned answered etc..
To increase the handover time another option might be to extend the duration of the contract and at the same time to benefit from the reduced rate that FCL can offer for a longer engagement.
How can I be sure of confidentiality?
FCL respects the clients' proprietary work and assumes the highest level of confidentiality.
Always. FCL is happy to sign any reasonably worded confidentiality agreement with the client.
What is your company philosophy?
To provide a consistently delivered and highly professional service.
Do you provide services directly or through an agency?
Either. If either the client contacts FCL directly or vice versa, and this results in FCL providing the client with services, FCL will
normally invoice the client directly. An exception might be in the unlikely event that FCL has a current exclusivity agreement with a particular agent relating to that client.
If that is not the case, then no agency will be involved. The client would therefore save any
fees that it might have had to pay to an agency. However FCL recognises that many clients have already outsourced all or part of their human resources and may have a list of appointed agencies to handle their recruitment requirements. In these cases FCL will work through the third party nominated.
How much will you charge?
A competitive market rate. This may be per hour, per day or milestone based, whichever the client prefers. FCL can offer a discount for a longer engagement (the 6 months'
rate will be cheaper than the 3 months'). The savings in time and travelling expenses for any off-site work will be passed on to the client
by way of a reduced rate for the periods concerned. Of course, these will also contribute to
reduced traffic congestion, emissions, less damage to the environment and extra available time to
support the client which
would otherwise have been spent travelling.
Why can't you give me more details on your work with client X?
The details of FCL's work with all clients are strictly confidential, even if no formal confidentiality agreement has been signed. If a prospective client wishes to get in contact with one of FCL's previous clients then FCL will contact the
former client and, once permission is given, pass on their contact details.
What facilities do you have?
FCL runs a laboratory equipped for electronics design and development work
currently up to about 6 GHz. For higher frequencies, test equipment is
hired as required. Many clients prefer FCL's representative to work on their site but FCL can offer cost savings for any work that can be performed away from the clients site.
Off-site arrangements would typically include agreed hours of work, full
contact information and regular progress reports by
teleconference or email and perhaps weekly face to face meetings. This of course results in
saving the client's resources in additional to protection of the environment by avoiding unnecessary travelling.
What policies do you have in place for protection of the environment?
When on the clients' site, FCL will of course comply with the clients environmental policies.
FCL's own environmental policy includes the following:
- Using public and other energy efficient transport instead of car travel, wherever this is possible.
(For two local contracts extending to more than 3 years, the transport for
travelling to and from the client's site was a bicycle.)
- Working with the client to allow, where possible, travelling during off-peak
- Using wake-on-LAN (WOL) and virtual private network (VPN) technology to use
the IT facilities of FCL whilst away from the office.
- Retaining technical papers and articles in searchable electronic form.
- Adopting an in-house repair policy for electronic equipment wherever possible.
- Donating obsolete but serviceable equipment for educational purposes.
- Recycling electronic components for development work.
- Avoiding unnecessary travelling to meetings where the process can be undertaken by email, telephone or fax.
