Hi All I have never had a problem with N Connectors. Had soldering problems with UHF plus there are a lot of nice switches that have N connectors, that are good bargains. Don't go to XYZ9 for your switches. My 2 cents N7RT

L Before putting any kind of tape, gunk or goo on a fitting or soldered connection with the expectation of weatherproofing it in an outdoor environment, I ALWAYS do this first: I wrap the item with two layers of half-inch wide 3-M blue tape used by painting contractors and widely available. This product has very little tensile strength, but that is not needed in this application. Its virtue is that, unlike almost every other tape, the adhesive never separates from the tape backing, with the result that even after years the protected item will be kept squeaky clean and uncontaminated by whatever was placed on top of it during the initial weatherproofing treatment. I learned this after suffering the vexations of using liquid solvents in often unsuccessful attempts to fully clean up and disassemble a fitting or soldered joint covered with a variety of weatherproofing products, parts of which had migrated into the connection, mechanical or soldered. 73, Charles, W2SH ________________________________ From: Topband <[email protected]> on behalf of Art Snapper <[email protected]> Sent: Thursday, October 20, 2016 9:16 AM To: 160 Subject: Re: Topband: inv. L I had a few hours free yesterday afternoon, so I began the dual 80/160 radiator inv. L project. In the process, I found that water had entered the coaxial center insulator that was used at the feedpoint of the antenna. Does anyone have a favorite solution for a weatherproof, coaxial feedpoint for this type of antenna??? The radials are attached to several load center ground bars, that are screwed into a copper pipe that is driven into the ground. The pipe gives me a rigid mounting point for some kind of insulator or standoff. BTW, after a temporary fix, I ran some quick SWR tests. There appears to be very little interaction between the elements. At least from an SWR perspective. de Art NK8X ?
