I’m rather busy reviewing two radios: the Baofeng GT-3 and the Zastone ZT-2R. I don’t want to get into too much details about my findings, but one thing deserves a blog post of its own: the Baofeng GT-3 stock antenna.
The antenna proves to be far from efficient and more or less kills the radio’s potential. I also felt that the antenna was running very hot at the base.
I connected a temperature probe to the base of the antenna with duct tape and measured three states: receiving at room temperature, temperature after one minute of transmitting and after three minutes of transmitting.
It’s clear that a lot of the energy is not radiated but converted into heat instead. This does not occur when I use a good antenna, such as the UV-B5 stock antenna or a Nagoya NA-701.
