Aftermarket antenna testing with the Ailunce HD-1 handheld dual band transceiver

With a wide variety of after-market antennas available for all sorts of handheld radios, I wondered about their true performance so I took an Ailunce HD-1 dual band VHF / UHF handheld transceiver and looked at a selection of antennas available.

In this video I look at the effect on ERP by comparing the aftermarket antennas against the stock antenna supplied with the transceiver. They are measured using a reference antenna 1 metre away and a spectrum analyser. This first video examines the performance on the 70cms amateur radio band at 433.500MHz.

Further videos to follow will examine the performance of the antennas on the 2mtr amateur radio band as well as harmonic and spurious content of the transmitted signal when using an after-market antenna.
