Leak around antenna

We're getting ready to head south after Christmas and I noticed a little line of water running across the floor after a night of heavy rains. I think that I have the leak traced to the antenna mount. There is a pin hole at the bottom of a small indentation and a small 1/8" crack at another point.
I bought some silicone sealant and some spray sealant and was going to put those on today. After sleeping on it I decided to ask those who might actually know what they're doing what they would use.
Our local RV place is closed for the winter. What's on the antenna now as a sealant looks like a grey putty that hardened.
Is there something that I could pick up at a hardware store to reseal the antenna that would be better than silicone?

Don't use silicone caulk on you roof.
On the top of the antenna base is a small rubber plug, remove it and put a squirt of silicone spray lubricant or a drop of oil in there and replace the plug.

Get a tube of Dicor self leveling caulk from a rv dealer. Clean the area with a non petroleum cleaner and apply the self leveling caulk.

I have a different take on it. For really small stuff a bit of silicone is just fine. The trouble is that the small stuff is the beginning of something bigger. The seals are drying up.

For bigger stuff use either Dicor or Eternabond tape. Dicor will only last just so long, so if you are keeping the trailer for a number of years Eternabond tape is a longer lasting more permanent seal. Whatever you choose you have to properly prepare the surface or it'll be a waste of time.

I would also stay away from silicone on the roof. If you ever want to re-seal with Dicor or EternaBond, you will need to remove the silicone first cuz they won't stick .

Hence the need for good preparation. Even if you never put silicone on your roof, you still have to properly prepare the surface. That includes removing any old material, be it Dicor, silicone, or what ever. I've done this stuff, silicone on the roof doesn't hurt a thing.

Thanks for the ideas and information.

I tried some silicone in a pinch once and it did not hold up well.

These antennas are known to leak internally due to the o-rings going bad on them. I would dicor any obvious issues on the outside mount but also maintain the inner workings (shaft, gears, etc) as they need to be maintained on a regular basis. Check online for the procedure. Good luck!

See my note here from post #2. This will take care of most drips if coming from inside the shaft. No need to take it apart unless this does not fix it.
