TV antenna sealing

[JazzDad]

Hello all.

The PO admitted to driving off once with the TV antenna raised. I'm on the roof now doing the whole reseal thing, and the TV antenna base is bad. Much of the caulk was torn loose. I've removed what caulk remained. So, now for my question: should I just glob caulk all over it -or- should I lift the antenna bracket and put new sealant under it, too? AND, if you think I should reseal underneath, should I use some Sikaflex 221 under there or some grey butyl tape? (My gut felling is the butyl would deform less, and be less likely to squish out when I tighten the screws back.)

OK.

With more time I was able to find this: http://manuals.solidsignal.com/www-s...000%20TECH.PDF

Very tacky stuff almost like liquid nails, works pretty dam good.

I used gray vulkem 116 from Fastenal, looks great a year later.
