Hi Jim, Thanks for the suggestions, when I get a chance I'm going to lower the dipole and check for oxidized connections, 'dry' joints etc. The antenna has been up for a few years and could probably

Dear Warren, LF Group, Assuming you are using the same loading coil as before, another possibility is that the loss resistance of the antenna has increased a lot - with a tapped loading coil there is

Hi Warren that sounds familiar !! I think you are using covered wire, my guess is a break on one leg so that you do not have enough capacitance to resonate with the original coils. A top-band dipole

Hi Steve, Hard to say, I can resonate it as a dipole on 160 with my homebrew link coupled tuner - but I can't say if the settings on the tuner are the same or not. Don't do much 160 this time of year

Lets try that again...any changes in 160m operation when used as an ordinary dipole on that band? Steve / VE7SL Web: "THE VE7SL RADIO NOTEBOOK" at http://www.imagenisp.ca/jsm
