The trap vertical that was mentioned would probably be a real hassle to
tune-up on the tower.

The GAP Titan can be dumped out of the box, assembled (use a tape
measure to get everything as per the manual) and put up without ANY
fooling around. You *MIGHT* have to make a minor adjustment to get the
80 and 40 meter bands right with the lowest SWR centered in the middle
of the band segment that you operate most, but mine came out perfect
using the factory directions.

You are telling me that the measurements are the same for tower mounting?

Thank you kindly for all the info

I have a lot of wire, can make any dipole, I have this 50ft tower that I
want to make a dipole and omni on the top.

The omni I want to be tunable so I can use it on other bands such as marine
band, to communicate with my boat

I have the manual tuner with reflected power measurements, so that is ok. I
want to know what is better, the dipole fed with coax or fed with ladder
line. The coax will run out the house, past the alumninum siding and be
taped to the tower, the ladder line I can run out the house, past the same
aluminum siding but can keep away from the tower about 4 feet until it
reaches the top where the dipole will split it and run the longest length I
can (I have the room) so that I can utilize all the bands with my tuner.

All suggestions and advice are excellent and I hope to hear and learn more

thanks

A fan dipole has multiple dipoles with the same feed using spreader
insulators at the end of each shorter dipole. Full size 40 meter dipole
usually works on 15 with a tuner as it is not far from a 3/4 wave, and 80
might work on 10. I always wanted a full size cage dipole for 80 and 75.
This has several wires for broad band operation. HF Discone is another
interesting broadband antenna. You could use the tower as a support but
takes up some space.

Good luck

I'd have to dig up the instruction manual to see what they have to say
on that. However I do remember assembling it according to the
measurements given in the manual and the antenna worked fine mounted
with the bottom at eye level with me standing on roof. The antenna was
mounted on a mast strapped to the side of the house. I now have the
antenna mounted at the same height, but using the GAP tiltover mount
hardware attached to a short length of Rohn #25 tower against the side
of the house. I don't think the GAP Titan is very sensitive to height
above ground, at least as far as tuning is concerned. Angle of
radiation is probably another story....
