For ppl who really want to stay connected while afloat ( I dunno why
but they do). Useless Idea #3734

Put a T in the output of your VHF so your cellphone can be connected
to your VHF antenna waaaaaaaaay up thar on your mast. Since your 900
Mhz cellphone is even more line-of-sight than vhf, this will give you
more more coverage when you are a few miles out. In this case, I
expect coverage will then be limited by cellphone power instead of by
not being able to see a tower. I would expect to be able to get
coverage from 15 miles out. I once experimented, while standing on my
cabin top, I was able to use my cell phone while being 6 miles
offshore. Would a cell phone booster be illegal?

I have seen boosters advertised for some cell phones.

As for the VHF antenna, if it does come out to a multiple of the cell
antenna its gain would be so high, and its vertical angle so narrow,
that it couldn't be used in anything but dead flat calm, with no
ground swell. There is also the little problem of impedance matching
and coupling the phone to the coax.

The booster seems likelier to work.

I never said I had good ideas. However, I realize that somehow you
better disconnect the connection when the VHF or radar is used. I
also forgot about impedance matching (my god, alzheimers, I taught an
engineering lab on impedance matching once). I really don't know how
a radar antenna works on small boats. If it is just a rotating dish,
it oughta work with the right transducer.
