About a year ago , a group did this. They had a rpt on the coast and wanted there signal to stay landside. I have a copy of there posting, I'll look for it. Bernie

I have a crazy thought, but I want to get some opinions. Here is
what I am thinking, only becuase I can construct them very cheaply.
As opposed to using a verticle, what would I expect if I used 4 10
element verticle beams, one point to NWSE, coupled with a power
divider. My objective in
In Hawaii, we did something similar. Our UHF repeater was at the 10,023
foot level (Mt. Haleakala, on Maui). We wanted coverage on the north shore
of the Big Island (Hawaii) and good coverage on the major parts of Maui. As
such, we had one 5 element yagi facing south and one facing north, but

You still have to do the divide by how many arms to the power divider
cabling, as someone mentioned it weakens the overall rx department,
however I have tryed this with just 3 3 element beams using the tower as
the reflector and it seems to work pretty good, when the weather is a
sure thing we are

I have seen this done with 8 beams on a 300 ft tower at 450Mhz

But would not the gain of these antenna's compensate for that, from say a 3
DB to 6 DB gain verticle to a 13 DB foward gain, directed in each direction.
---It's not really that big a deal. I'm sure it will work fine as you
describe. The only caveat I have
Unless you can line up the radiating elements vertically, all your
antennas will be out of phase with other to any other direction.
Some RX signal will go by the first antenna and hit the 2nd 3rd and 4th
antenna out of phase with the 1st antenna. The end result is that the

My thoughts on this idea was to eliminate the need for the voting system,
save a few bucks, as this thing is coming out of my pocket, sad part is
momma has sewn the pockets shut, hi hi. But I think most of what is
