Hi Larry

Just a quick thought.

Since a moved from the marine band to 2m is down in freq you may get
away with something you can slip over the marine whip to increase C to
ground. I am thinking something loose here, not so much a metal to metal
connection. Since there will be a greater effect at the top end maybe a
piece of metal pipe just sitting close to the top, maybe buffered with a
grommet or something to hold it in place.

Might be worth an experimenting if the 2m VSWR on the marine whip is
beyond bounds!

Of course if you have the money to throw at it, mounting a high gain
vertical on a steadicam mount might solve the movement induced pattern
problems! grin

Hi Bob,

Well, after a bit of experimenting (and remember I'm almost always on an
inland lake) I decided to go with the Morad antenna. I've ordered one
and a mount - it will probably be here next week. I'm not too concerned
with pitch and yaw - it will be close enough to vertical!

Yes, I could detune a marine band antenna - for that matter, the SWR is
probably close enough, but this should work and there's some genuine
gain, but not so much I have to worry about keeping it vertical.

Actually, I'm lazy!
