Amplifiers can be found quickly and easily by using the Amplifier Selector page
Allows a DC supply current to be fed to the inner of a coaxial cable for remotely powered equipment.
Broadband Amplifier 1 GHz
This amplifier was designed as a quick solution for 'standing wave' measurements. It has turned out to be a most useful piece of equipment.
A very basic piece of kit but essential in some situations, especially where test equipment inputs cannot handle a dc component.
This amplifier is designed to cover the HF band with the optimum performance. It also covers the LF and MF bands and could be most useful to radio hams.
High Frequency Active Probe
A High Frequency probe designed to measure voltage distribution on an antenna but also suitable for other applications , such as fault finding PCB's.
Low Voltage Detector in a Micro Size FLEXI-BOX
Detects voltage from 0.3 MHz to 700 MHz at -30dBm to +10 dBm.
The RF Bridge is a directional device for splitting the forward and reverse components in a transmission line.
The stub filter can be used for the same tests with a spectrum analyzer as the RF Trap above.
This is intended to be a test aid and is also part of our Standing Wave Demonstration "Kit".
FLEXI-BOX Transmission Line Original size 63.5 mm
long x 50 mm wide x 30.5 mm deep
Mini FLEXI-BOX Transmission Line 50 mm long x 35 mm wide x 23.5 mm deep.
Micro FLEXI-BOX Transmission Line 35 mm long x 35 mm wide x 23.5 mm deep.
All of the transmission line boxes have a PCB with a 50 Ohm track running end to end. This is intended to be used to build surface mount circuitry by using a scalpel and a soldering iron to achieve the required layout .
VHF Broadband Amplifier in Mini FLEXI-BOX
Broadband amplifier designed as a test aid but equally suitable for a LF, MF, HF or VHF radio installation +10 dBm output.
VHF Broadband Amplifier in Original FLEXI-BOX
Broadband amplifier 3 MHz to 300 MHz +20 dBm output.
Measures voltage and current in a coaxial cable from 0.3 MHz to 300 MHz. A unique and most useful product.
Voltage Detector in a Micro Size FLEXI-BOX
Detects voltage from 0.3 MHz to 300 MHz with up to 10 Watts input power.
6 dB Splitter
This is a resistive splitter which gives good phase matching and low amplitude ripple to 3 GHz using standard 0805 resistors.
500 MHz Broadband Amplifier in Mini FLEXI-BOX
Broadband amplifier designed as a test aid but equally suitable for a LF, MF, HF, VHF and some UHF radio installation as it covers the frequency range 0.3 MHz to 500 MHz.
