160 Meter Dipole	Reply
by N9MXY on October 19, 2009	Mail this to a friend!
I did a search for 160M dipole and read some threads but found nothing that directly addressed my questions. I have room to install a 160M dipole that will be about 60' high at the ends. and over level ground passing over 1 35'maple tree about 20 feet from one of the ends. 1. Is this high enough to give me a decent angle of radiation without too much ground loss? 2. I only plan on using it for 160. Can I run ladder line to a 4:1 then maybe 30' of coax to the tuner without suffering too much loss? If I did do this would I gain anything by tuning the antenna with a coax run then installing the ladder line and balun?

If you feed your 160 meter dipole with parallel feeders you will not notice any difference on the S meter if compared to a coaxial fed dipole on this band. The losses are very low at these frequencies. If you don't have a good 4:1 balun, you may actually find the parallel feeder setup may even be worse. There are a lot of JUNK 4:1 baluns out there. If you want to use this antenna on other bands, then you must use parallel feeders. But it you are going to use this antenna only on 160 meters, coax is a lot easier to use. If you can only erect your dipole at a low height, do it anyway. Compared to no 160 meter antenna at all, you'll do just fine. Don't expect a true figure 8 pattern but who cares. You will be active on 160 meters and have a lot of fun. Barry, KU3X

If you're like most of us, you just don't have many real good options for a decent 160 antenna. "Ground loss' really won't be a problem. It's just not going to be a real low angle radiator, but if you can take the ladder line to the tuner, you'll have a decent antenna for all frequencies. A variety of patterns as you move through the bands, but nothing with much in the way of serious nulls on any of them.
