Remember to calculate in the rated gain on the antenna. A simple 3dB
gain gives an effective doubling of radiated energy. With sufficient
gain, you can overcome much of the feedline loss.

Are there any VHF antennas with N connectors out there?

Something has to give when you pull the mast
I used LMR400 coax cable when I replaced mine and there is a connection under

As someone that works with RF ALL DAY every day, my suggestion is to replace
the cable. Signal loss from splices and connectors, especially in the
potentially highly oxidizing / corrosive marine environments will or could
eventually- and most likely – render the radio useless. Always
I also have had good luck with the Shakespeare coax splice.

Charlie, better to terminate both ends with a pl259 connector and use a pl258
female to female connector to join them. Coax doesn’t splice well.
Shakespeare have a gold plated solderless connector that I’ve had good success
with, that provides a minimal loss.
