This reminds me, I would like to hear from others that have mounted an antenna to
the top of their P-19s. P-15 owners are welcome to contribute to this as well, but
I'm not sure how similar the mast tops for the two boats are. I'm thinking of
installing a connector on the top to which I can attach either a cap or antenna
before raising the mast. The coax would be run down inside the mast.

BTW, gain is usually referred to in db, not watts which is what power is measured
in. It's a function of reception, not transmission. SWR is the transmission value
you'd want to worry about as far as getting out from the antenna, along with using
the minimum amount of power to reach your target. Raising the antenna height
increases your range, since it's line of sight for VHF/UHF.
