As manufacturers of antennas and SAR equipment, the company has always believed it of great importance to provide supporting equipment to these products. Over the years, this has resulted in a range of Test Sets being manufactured by Techtest.
Our range of VSWR Test Sets is known throughout the aviation community as the industry standard products for testing aircraft antennas. They are all available with ruggedized cases and models are available to cover all the frequencies commonly found in avionic equipment. These VSWR Test Sets allow antennas to be checked for correct operation and can be used whilst the antenna is still on the airframe thus saving costly removal of the antenna when it is not necessary.
It is vital that an Emergency Locator Transmitter works correctly, if it is used, so Techtest supply a range of test equipment to check correct operation of this type of equipment. These Test Sets can be used with all types and makes of ELTs and EPIRBs.

The 503 Series of automatically activated Emergency Locator Transmitters are the most advanced on the market yet are available at competitive prices. All 503 series Emergency Locator Transmitters are designed to work with the COSPAS-SARSAT emergency satellite system and operate on 406 MHz in addition to the two traditional distress frequencies of 121.5 MHz and 243 MHz.
They are available as an Automatic Fixed Emergency Locator Transmitter or Automatic Portable Emergency Locator Transmitter depending on which mounting tray is specified. The 503 series of Emergency Locator Transmitters has been fitted on all types of platform including GA aircraft, helicopters, commercial airliners and military fast jets.
By using the latest in solid state microprocessor technology coupled with an advanced battery design, we have developed the smallest and lightest automatic Emergency Locator Transmitter currently available. This has not been achieved at the expense of the outright specification of the Emergency Locator Transmitters as they offer a number of unique standard features and options. They are the only Class 1 Automatic Emergency Locator Transmitter available ensuring they remain fully functional down to temperatures of -40Â°C. They also include a sophisticated self-diagnosis feature which along with their modular design ensures trouble free maintenance.
The 503 series of Emergency Locator Transmitters can be interfaced to the aircraftâs on board GPS system, without a separate interface unit, to ensure even faster detection times in the event of an emergency. All common GPS protocols are supported, and for aircraft not fitted with GPS the 503 series of Emergency Locator Transmitters can be specified with its own embedded GPS card.
Techtest are the leading manufacturer of Automatic Deployable Emergency Locator Transmitters, supplying all the leading helicopter manufacturers and off shore operators. These systems are part of our 503 series and offer a top quality solution for all maritime aircraft whether commercial or military.
The 500 series of Personal Locator Beacons or Survival Emergency Locator Transmitters offers a wide range of options to suit any requirement. The 500 series of Personal Locator Beacons has been chosen by a wide customer base, including armed forces, commercial airlines, off-shore helicopter operators, life raft manufacturers and ejection seat manufacturers.
For all the 500 series Personal Locator Beacons, Techtest has obtained full certification to aircraft standards so these products should not be confused with inferior quality beacons intended for hobby use.
The 500-1 Personal Locator Beacon is a compact light-weight unit operating on 121.5 MHz and 243 MHz and has been favoured by customers requiring a small beacon for many years.
The 500-12 Personal Locator Beacon is designed to work with the COSPAS-SARSAT search and rescue satellite system and features 406 MHz as well as 121.5 MHz and 243 MHz distress signals. It also incorporates a speech function which allows survivors to have two way voice communication with a rescue craft. In addition to the normal aircraft approvals the 500-12 also has full Boeing and Airbus approvals making it the natural choice for commercial airline operators due to its compact size and low weight. The 500-27 shares all the functionality of the 500-12 but also incorporates embedded GPS to minimize location time in the event of an emergency.
The latest 500-27-07 PLB (above right) utilizes all the proven electronics of its predecessors but updates the casing design to give a modern stylish appearance without losing the rugged and durable qualities associated with Techtest SAR products.
The new 500-32 PLB (above left) offers similar features to the 500-27-07 but in a significantly smaller package (35% reduction in volume). This has been achieved by using state-of-the-art battery technology and optimised electronics.
After rigorous testing the 500-32 series of ELT(s) or PLB has recently been awarded a COSPAS SARSAT type approval (Certificate No. 223).
500-30, 406 MHz Ejection Seat Compatible PLB
The 500-30 is the latest member of the highly successful Techtest PLB range offering 406MHZ transmission and Guard frequency transmission combined with embedded GPS to provide positional accuracy of 100m.
With both manual and automatic activation capability the beacon offers maximum flexibility across a fleet of aircraft. Providing interface solutions for inclusion in PSPs within ejection seats such as ACES II/III and in combination with parachute activation mechanisms such as the BA22. Once activated upon ejection the PLB will transmit SAR frequency signals via remote antennas allowing rapid recovery.
Once on the ground aircrew can continue to transit using remote or integrated dual frequency antennas including GPS providing portable functionality and the ability to control beacon transmission according to circumstance. With 5 year battery life, 48 hours transmission on 121.5MHz and 24hours on 406MHz at -20 Â°C the 500-30 meets COSPAS SARSAT, ED-62A, STANAG 7007 and MIL-STD 810F specifications.
