3.4 GHz Ham Radio test with WA5VJB Log Periodic Feed - VK7HH
I received a log periodic antenna designed by ham radio operator WA5VJB from Kent Electronics. They are rated from 2 to 11 GHz, so this model will cover several of the ham bands. These antennas are made on PCB's and are ideal for use in the amateur microwave bands as compromise dish feeds. In this video I do a test of such a feed versus my patch antenna on the 3.4 GHz band.
TYLKO ZAREJESTROWANI I ZALOGOWANI UŻYTKOWNICY WIDZĄ LINKI. DARMOWA REJESTRACJA
I mounted one in place of the original dipole feed on a 2.4 GHz (13cm) gridpack at the same focal point. Whilst gain will be down a bit on 3.4 GHz (9cm) results were surprisingly good, although smoke started to come off the PCB at a power level of 20W FM! In this video I have a contact with VK7ZBX whilst portable. Again this was a non line of sight contact.
