Trevor What you describe is very similar to the set up that I have here. I have a 65' mast with a 10' horizontal fibreglass pole just below the top. My 66' 80m quarterwave runs up to one end of the fibreglass pole and the 160m inverted L to the other side. So the two aerials are 10' apart in the vertical section and fed with separate coaxial feeds. It works really well. The secret, of course, is to maximise the number of radials that you can get down. My 20 radials are woefully inadequate, but I'm not going out in the snow to put down more today!
(There's a picture on my QRZ.Com page, if you wish to see what I describe above.) 73, Ian G4IIY -----Original Message----- From: Topband [mailto:[email protected]] On Behalf Of Ray Benny Sent: 29 December 2014 00:53 To: MR TREVOR DUNNE Cc: topband List Subject: Re: Topband: 160m L and 80m Vertical Trevor, For 160m I have a 75ft irrigation pipe vertical (4 & 3 inch pipe) with two 50ft top hat wires wires. For 80m I run a #10, 65ft wire with 12 inch homebrew fiberglass stand offs up the side of the irrigation pipe. At the base, I have two separate matching devices that I manually change to operate either band. I will automate this soon. This way, This way, I can share the same radial field. I do have to ground the irrigation vertical to operate on 80m. Works great for me!
