Antenna Development Projects
Our key resource is our highly skilled and experienced engineering team.
With years of design and development of antennas, they will design an
antenna to meet the specific requirements of our customers.
New Product Design
Where we do not have an existing antenna we are able to offer a full
design service.
Our engineering team has a wide range of modelling software to assist
their knowledge and experience in the development of new products.
This allows us to predict the performance of an antenna at an early
stage of the development programme.
Our manufacturing and engineering workshops allow the efficient
production of antenna prototypes which are then tested in our near
field spherical anechoic test chamber. It is our normal practice to
manufacture a prototype as part of a development programme.
Our engineering and technical staff work closely with customers to
develop an antenna solution, quickly and cost effectively.
Product Modification
If one of our many standard antenna designs (as listed in this brochure)
does not quite meet a customer’s exact requirements we can modify
the product. This may include a change of connector type, flying lead
rather than connector, a slight frequency retune, or an alternative colour.
We are able to make cost effective adjustment such as these, in a short
timescale, in order to meet requirements.
