When I was building slotted waveguide antennas for our network, we needed a way to seal up the slots so the rain wouldn't fill the antennas faster than a weep hole could drain it. I found that 3M made some heat shrink tubing that just fit over the size of tubing I was using. After heat shrinking the stick, we would dip the ends in "plastidip". Never had a leak. I wonder if you just needed to hand make a couple dipole or patch array antennas, if dipping them in plastidip wouldn't be a decent option. Obviously it would be labor and time intensive for production, but for a couple one-offs, why not?
