I suggested a simple 1/2 wave J-pole antenna earlier that was easy to
make, super easy to tune and one that worked very effectively. Yet
everyone is beating their brains out trying to come up with the best
5/8th wave J-pole, even though this design will require lossy matching
devices to get the impedance down to a manageable/acceptable level.
What's up wid dat?

Until recently, I owned an all fiberglass houseboat--beautiful rig.
However, on fresh water it offered no counterpoise properties whatsoever.

A continuously loaded 1/2 wave end fed vertical utilizing a modified
gamma match feed ended up the solution, and one which required a minimal
counterpoise.

Yeh, Larson makes an antenna that is designed for(insulated) vehicles
(thinkit is the "OS" series, 1/2 wave) , and also, it is possible to use
regular 1/4, and 5/8 wave antennas on such, useing Burglar alarm, or
"Waterproofing Repair Tape" ( 2 Inch aluminium tape), available at
Home Depot, or Lowes. Tho NOT at a 45 degree angle, should make a
adaquate counterpoise for your antenna, and can be on either side of
the roof! Give it a try! Jim NN7K
