Hi there! Some of you may remember that I used a RH-770 antenna for my handy-talkie. I found out that the one I had been using was a imitation. So, I obtained a Diamond brand RH-770 antenna from Blazer Electronics Center in Sim Lim Tower. That being said, if you are in Singapore or manage to get a chance to come, you should visit the shop one of these days!
It is located at the basement, for your information.
So, here are the 2 antennas side by side. Can you guess which one is the imitation? π
So, Mr Jeff used his Anritsu Site Master to test the performance of the antennas. Here are the results of the imitation antenna.

So, the old saying is true, you get what you pay for! The Diamond RH-770 works well on both VHF and UHF bands! Definitely will recommend people to get this antenna for their handy-talkies if I can.
Anyway, thanks for taking your time to read my blog!
