I'm thinking of installing an end-fed half-wave dipole as an "inverted U" for 160m. My tree geometry is such that the antenna would be fed at the base of a tree, then go up it to 120 feet. Then about

Hi John, Horizontal polarization isn't very effective on topband except for local QSOs. It would be far better if you could install an inverted-L vertical 73 Frank W3LPL -- Original Message -- I'm th

John, your 80M dipole with 110 foot vertical feedline fed as a top-loaded vertical on 160M is a wonderful antenna. If you are unhappy with its receive performance,the solution is to add a receive ant

Thanks for the info guys. If only I had room for a dedicated rx antenna - then I'd leave the top-loaded vertical as is. I was copied in New Zealand with it on 630m WSPR with 1 watt ERP. So a happy me

Last year I used my 80m dipole-110-foot vertical feedline as a top-loaded vertical on 160 - it worked well as a transmitting antenna but was a poor receiver due to noise so looking for another option

I would never consider compromising a TX antenna just to hear better. Perhaps a T vertical with a feedline choke similar to your 80m dipole and feedline radiator footprint would help with any local n

All I have been running a 160M Inverted L right up beside some pine trees to the 80ft level and then I have the horizontal part moving away. The support for the vertical part is in the tree it runs u
