E-Field Active Antenna

This project is being implemented by the Goole Radio and Electronics Society. The antenna uses the modified PA0RDT Mini-Whip design. The PCB and component kit was put together as a kit by the late Dave Powis G4HUP and now sold by the UK Radio Astronomy Association. The kit only includes the electronics.

Radome with cap
Probe support bush
PCB from UKRAA kit, assembled with a soldering iron and 0.3mm solder
PCB inside the collar. It will be potted to prevent moisture damage
Collar fitted to the mounting pole and radome. All sections will be filled with PU foam once tested
