Sprays, coatings etc. are fine if you plan on never taking the connector loose. If you apply a layer of 88 tape first, fine, spray and coat as much as you want. If you want to take the joint apart, just use a knife & cut thru the coating and tape and peal apart. But with the spray alone (or Coating) good luck removing the connector. Same goes with the 2228 tape. It forms a great seal around the connector, but if applied directly, with out a wrap of 88 first, is difficult to remove after baking in the sun for a year or more. Since most hams want to be able to work on their antenna systems, being able to remove an antenna connection is a plus. On commercial sites, it is not as important to allow for future antenna change, so waterproofing is some what different depending on antenna , connector, feedline and such.

Been thinking about putting a connector together and spraying it and spending some time in some some water maybe some salt water so I could read any change for the new meter also look for loss of have a throughput or increased loss using the antenna analyzer should. When I first got into commercial radio some tower hands taught me their method that was the wrap the connector with a layer of upside down tape so that it wouldn’t stick and become gooey then the layer of Butor rubber each one getting a little bigger than a layer of electrical tape again this time gooey side down and then cover that with something called the scotch liquid tape. Most of the connectors I seen that were in the field for a while however the liquid Cape and tape at most of the connectors I seen that were in the field for a while however the liquid tape it cracked badly and wasn’t performing well but I’ve never had a white connector in many years of dealing with towers.

Next add a layer or 2 of the 3m 2228 Tape then outer layers of 88. Always use 3M 88 tape outside. It is rated a higher temp than 33. Never use a cheap store brand or no name tape (Imported) as it will come off as a stickie mess if you ever have to remove it and will not last in the sunlight. 3M 88 will cost $4.00 or so a roll where the cheap tape, you get 10 rolls for $5 but you get what you pay for.

Tape it around the PL connectors. There are other kinds, but this one you can find at Lowes or HD pretty easy.

I hung it yesterday (before all of the rain) and was able to tune it on every frequency with my Yeasu FT-991A and make several FT-8 contacts. It seemed to be working very well. This morning, it will not tune on 80, 40, 30,17. Any clues on what is going on? This is the second time I’ve had this issue - last time it wouldn’t tune on 40 & 30 - I thought it had to do with being to close to the house which is why I moved it. I sent it back to the person that made it and they checked it out and sent it back to me.
