Re: VHF RADIOS's ...Opinions
The cable can be shortened in 2'4" incriments. But try to mount the antenna as far away from the rig as practical. Expect a reliable range of 20miles on high power (25Watts).<br />I reccommend you go with the 8foot whip, and have the SWR checked at a radio shop or ham radio operator.<br /><br />Also, when installing anything electric or electronic, get the ground potential checked. You may have to put a bigger zinc on your boat to compensate.<br />"Single side band" or SSB is a totally different beast. They operate on a much larger antenna,and lower frequency. They have unbelevable range, but are also unbelievably costly, and require a licsence from FCC. <br />VHF and SSB are different modes too. VHF is FM or Frequency Modulated,meaning the frequency itself varies with the voice.<br />SSB is Amplitude Modulated, meaning,the level of the voice changes the level of signal. The bottom line is ;<br />VHF is good for reliable comunication for 20miles,and high quality audio. Less paperwork,and cost.<br />SSB is good for reliable communications for 80 miles,subject to atmospheric influences ,can sometimes communicate around the world.
