RF is interesting, so keep asking questions like many others should. You will find that some people will tell you things that are not true, or are true to them. It is obvious you are ahead of others by coming here and asking questions. If you want to make sure your system is doing well, ensure you’re using at least LMR-400 or LMR-400UF coaxial cable from your radio to the antenna before you consider a slightly improved antenna.Īlso, congratulations on your license and welcome. It does offer some claimed 2dB gain, but that X50 is probably fine plus it has less wind load.Īs to 4 meters above the roofline minimum to use the X300 does not make sense to me, unless you have nearby terrain/structure you need to get above. ![]() If you are able to use the repeaters you want using the X50, there may not be a reason to spend extra money on the X300.
