I now use white Lithium grease in most of these applications. It's good and it stands up to the elements quite well. I have a rather large array "up there" and went through a pair of HDR-300s in just

Hmm... Interesting, I didn't expect to actually end up with a superscript. I used the "up arrow" to indicate superscript and the posting actually turned it into superscript. 73 Roger (K8RI) _________

I just gave away 200 feet of LDF4-50 with two new connectors. Often you can find it used, in good shape "with connectors" for very little. Of course when looking for heliax I look for the 7/8" as at

Did you start at the bottom and work up? If so the problem should be at or just below the point where the shield turns shiny. It gradually turns gray with water and water *usually* works down the coa

Hardly. I'm comparing a lumped inductance in the center to turning the entire antenna (or most of it) into one long linear loaded antenna. Yes, that's what center loaded does to get the required indu
