H.R.SMITH GROUP OF COMPANIES
Since its formation in 1965, the H.R.Smith Group of Companies has opened
up a whole new horizon of advanced technology through the development
of a wide range of specialist materials and equipment.
Designed to revolutionise the efficiency of military and civil airborne
and land communications, navigation and special functions, H.R.Smith Group
expertise leads the world in material and product superiority across a
wide spectrum of activities.
The Group also has a distinguished international reputation for high performance
advanced thermoplastic structures, microwave antennas and components as
well as test instrumentation.
H.R.SMITH (TECHNICAL DEVELOPMENTS) LIMITED
Designs and manufactures a complete range of airborne antennas for fixed
and rotary wing platforms both civil and military.
Supplies electrostatic dischargers for complete noise quietening of all
types of aircraft platforms. H.R.Smith (Technical Developments) Ltd specialise
in low weight, low cost, fully approved electrostatic dischargers for
commercial aircraft use.
Conductive sealing gaskets for the often neglected antenna to aircraft
interface for all types of manufactured antenna worldwide.
Techest Limited manufacture a full range of internationally certified
Emergency Locator Transmitters (ELTs), Personal Locator Beacons (PLB)
and Automatically Deployable Emergency Locator Transmitters (ADELT). Used
extensively with the world wide COSPAS/ SARSAT rescue system. Latest versions
have in built Global Positioning System (GPS) for enhanced rescue.
Techtest also offer a full range of Search and Rescue (SAR) systems to
locate personnel in distress for both civil and combat SAR use.
In addition the company manufacture a range of test equipment specifically
for testing aircraft antenna in situ, along with a primary attenuator
standard for the National Physics Laboratories.
Specmat's unique combination of advanced design and manufacturing technology
plus R.F design know how places it at the forefront of advanced thermoplastic
The new generation of advanced engineering thermoplastic has enabled Specmat
to create advanced reinforced structures which have unique rain erosion
and impact resistance, high temperature capability and thermal stability,
superior electrical and mechanical properties and enhanced chemical resistance
all at an affordable price with on time delivery.
Specmat continues to supply world wide, aircraft radomes and structures
for both civil and military applications.
