I could not find any reviews on this antenna so could anybody from the RR community give me some feed back please.
Not sure you will find many reviews.
Keep in mind that there isn't anything magical about how antennas work. They are bound by the laws of physics, and so far no company has found a way around that. Since it's a 1/4 wave antenna on a portable radio, it's should work just as well as any other 1/4 wave antenna on a portable.
Really, there are only two variables here:
1. build quality. Is it a well designed antenna, good connector quality, not going to break first time it flexes?
2. is it actually resonate where it claims to be? Not uncommon to find cheap/off brand Chinese made antennas that are nowhere near resonate on the frequencies they claim to be.
Tessco is usually pretty good, although I've got a few crappy products from them when I've tried to go cheap.
Terra-Wave has been around for a while, so unlikely it would be a real piece of excrement.
Based on the price, it's kind of hard to go wrong. The big issue you'll have is Tessco has a $50 minimum order, so unless you are planning on buying a bunch of these, or need other supplies, you'll need to fish around.
