I painted it Sky Blue to blend in with the sky on nice days..... do I need to put something around were the coax screws onto the antenna???? I was going to fill it with electricians' putty but it looks like maybe there are drains??? but DO I NEED to put anything on it???? the connection is pretty recessed so pretty hard to get to it... they only leave a little area to screw it on... I know they sell tape and stuff.. but do I NEED anything???? 32 foot pole looked a lot shorter in my mind and I found out wrestling that up onto the side of the garage is not a one man job.... so after it is up... it's not coming down again... so whatever I need to do, to the connection I want to do it now. thank you all
I have a lot of questions regarding grounding and such but not sure exactly what you're doing here but to answer your specific question, I'm a dinosaur so..
There is definitely something I use which is an old product and I know there's better stuff out there and I'm sure someone will chime in with it but I like to use something called coax-seal, it comes in a roll and it's a putty like sealant.
After you screw on your pl-259 tightly on the antenna before you rap the connection with the gooey sealant you would want to use electrical tape first, not as a sealant but if you ever want to remove the pl259 it will be a lot easier with the electrical tape underneath. You would just take a medical clamp, you know, like to clamp off veins and arteries in an operation it's a common tool used in radio, I advise using one of those straight or curved but you're going to want to get the wrapping of the electrical tape all the way to the top of the pl259 plug. I guess a very small needle nose pliers would work too or something else that small enough to get up in there.
When you apply the sealant it's the same deal, start at the very top and wrap it around the whole pl259 connection using a clamp or pointy nose pliers so it's nice and tight and you can actually mold it with your fingers as high up as you can go or using maybe a wide nail file. You have to improvise here so that you get a nice thick tight waterproof wrap around the connection.
Water getting into your coax is the worst problem and it's pretty common if you don't protect connections with some kind of waterproof seal.
You can buy the clamp at any medical supply store as nurses use the clamp every day to clamp off IV tubing and other types of tubing. They're easy to buy. Look up the coax-seal on the internet and you can have it in a couple of days.
Use good quality electrical tape underneath, if you ever have to unscrew the pl259 all you would have to do is use your clamp and unravel the electrical tape and all the goo will come with it, without the tape you're going to have nothing but a mess if you tried to remove the pl259.
Not sure about painting your CB antenna, don't know what that'll do to performance. I don't know, I have never seen that done.
