Dear fello hammers!
Thanks for the help in advance
I am going to be installing a wire antenna, I want to mainly use it for 160m and 80m, and not sure which type to install, my head is spinning !
Here is my situation, the feedpoint centre of the antenna will be 250 feet away from the shack, and I can only use coax from the shack to approx 150 foot towards the antenna, due to there are some buildings in the way that I have permission to clip the coax to, so I cant use open wire feeder as it will literally be tacked to the buildings for at least 150 feet
For the remaining 50 feet, I could still use coax or at that point I could change to feeder
Due to the long run, I think the antenna the coax is connected to needs to be resonant on th bands I want to use, if not resonant then there will be horiffic losses due to the long cable run, right ?
So my thoughts are installing a fan dipole for 160m, 80 and 40 so its resonant and therefore no high SWR and no real losses. Would you agree with that ?
I have approx 350 feet in a straight line to install the wire antenna on, so 160m dipole can easily fit.
I could install an end fed and get some good radials down, I could install a doublet but think thats not workable due to the coax swr and losses problem. I could install some loops as I have 350 x 350 foot space, but the first 150 foot must be coax fed.
I could get away with two coax runs to feed two antennas but the coax leads would be touching each other.
I could install two seperate fan dipoles on the same mast, on the same coax, that way I get 160, 80 and 40 on one, and 40 20 and 10m on the other, both on the same mast, on the same coax.
How about a multiband 160m to 10m trapped dipole, would that work ?
Any suggestions ?
What would you do in this situation ?
What I wwant is the best antennas for each band
