TYT TC-3000A Stock VHF Antenna/Tuned Antenna Comparison
Channel: Mountain Parameters

You probably don't need to actually watch this video, because what it demonstrates in 12 boring minutes can be summed up in about 12 seconds of reading. And that is, if you buy a Part 90 FCC approved VHF radio offshore that comes with a standard rubber duck antenna, and you plan to use it on commercial frequencies above 155MHz, you may need to reconsider. Yes, the base of your stock antenna may indeed have something like 136-174 MHz printed on it, but as 'She Who Must Be Obeyed' has reminded me, the chances that that is a plausible axiom is every bit as ridiculous as me looking in the mirror every morning and trying to convince myself that I don't look a day over 60.
