Terry, I have both vertical (shunt fed tower) and horizontal (loops,
dipoles) antennas for 40, 80, and 160 -- and find that the dipoles work
better for the local QSOs and the verticals work better for DX. Do whatever
you can to get the tower as high as possible. My son had an old CB 102"
mobile whip that I strapped to the top of this tower to make it 8 feet
longer.

Shunt-feeding the tower is pretty straight-forward. It's a lot easier to
accomplish with an antenna analyzer (I use an MFJ 259) but you can do it
with just an SWR meter.

I would refer you to ON4UN's book, "Low Band DXing" -- great reference
material.

Hi! To make a long story short, I will be moving my beam to another
tower, and will have a rohn 25g tower that is imbedded in concrete
approximately 50 feet away from the house. I would like to get a
decent lower band antenna (not 160). I'm wondering what would be the
best scenario:

1. Put up a mast above the 32 feet of tower and hang an inverted V
(Alpha Delta 80/40) and 30 meter inverted V (common feed). It would
be up around 40 feet.

2. Put my Butternut HF2V vertical up on top of the tower and put a
few resonant radials for 80 and 40 on it. It wouldn't be guyed
(important here in NW Iowa). I thought about even using the 80/40
dipole as part of the radials since I already have the antenna.
(Anybody have any experience with loaded radials?) My HF2V vertical
ground mounted didn't seem to cut it the last two winters...

3. Load the tower for 80, 40, and 30. I would need some guidance on
how to build a gamma match for this situation. If I went this route,
It would probably not work well for 80.

4. Extend a mast on top, and string some sort of Inverted L's for 80,
40, and 30 and put ground radials at the base.

My primary interest is to increase my DX totals especially on 80 since
I already have DXCC on most of the other bands. I have a decent
antenna for the higher bands.
Thanks
