The goo can be left on the part thats inside the connector. I use lacquer thinner to remove any thats external otherwise its both annoying to handle as well as attracting anything from bugs to wind b

I guess I should be thankful that all mine are run on land that maybe has a 10' variation but it is all heavily wooded. I also look carefully at the antenna path and try to avoid trees that slope in

Thats fine for single wire installs, making and installing spacers for a 2 wire is a pain and likely far from a perfect balance. Carl KM1H _______________________________________________ UR RST IS ..

I believe the problem with that was covered in one of ON4UN's books or elsewhere. Transposing, aka twisting, is automatic with most of the 2 wire cables in use.W8JI and others claim it improves the b

** Wide spacing is also more prone to unbalance wheras close spacing and twisting promotes good balance. ** That barely qualifies as a subjective test and 300' for Topband isnt that directive/effecti

It all depends upon how much survivability you want, nothing will survive a direct hit. Any 1.5 to 2.5 mH choke will suffice, just look at the safety choke in a commercial amp for the smallest choice

That is only 226 Ohms at 1.8MHz and at 1500W will be dissipating about 30W in a 50 Ohm system but Phil didnt say how he is feeding his tower which is resonant well below 160M. Yes it will work as wel

That doesnt work for us that have solid rock as the tower base. My 180' has solid granite at 8-14" below grade and the other 3 towers arent much better, I think the deepest spot is 2' of sandy gravel
