You didn't mention how long your run is, and how much savings you are talking about. Personally I quit using untinned wire of all sorts on boats, freshwater, or salt
...and not just coax. So I'd vote for the good stuff. Don't forget to use coax seal wrap on your finished PL-259 connection at the masthead. Also, and you may know this already, do not forget to solder the coax braid to the PL-259 coax plug
. When I was in the business I used to get more than a few "intermittent" VHF radio
complaints, where the problem was not the radio
at all, but the fact that the owner had installed the PL-259 coax connector and only soldered the center conductor! The braid eventually corrodes and there you go---intermittent.
Lastly, you probably don't want to hear this part. If you are considering saving money
by using the skinny cheap
coax (like 52 ohm RG-58), you'll find the signal attenuation on longer runs could cut your effective radiated power back quite a bit when compared to say RG-213x (the large diameter silver double braided coax). So it's possible you think you're getting 25 watts out of your VHF antenna
, but your effective radiated power ends up being much less because of the loss in the skinny transmission
line. There are attenuation specs listed for all the different coax types you are considering so you should look those up. They will be listed as so many db loss per 100 feet and also at certain frequencies. Marine
VHF is around 156 MHz. Of course as you've already found, the better stuff is a bit more pricey. Good luck. Maybe someone else will chime in with some actual numbers vs. price
, but I've been away from this stuff for a long time now. Good luck...
