Try some citrus based solvent.

Hello All,
From what I have seen the quality is the same but I have been preaching
on this board and others you cant install a DB antenna without sealing
every screw, bolt, plastic knot, connector and anything else that could leak
water. Besides that you must take all connections to the harness and
tighten all screws before you seal it. Once you do that the antenna may
possibly outlive most people on this board. I have a DB-410 in downtown
Fort Worth that I installed in 1976 and it still has flat SWR.
Use Scotchkoat from 3M to seal the antennas but dont get it on you, it
sticks to you as well as it does the antennas.

YES!
Recently replaced a new DB-224 that had wicked water in the molded
harness section and ended up inside the connector. Upon receiving a
replacement antenna, we sealed the heck out of the harness with vapor wrap
before installation. This one seems to be holding up for now, for now knock
on wood. The local PD did not like a water logged antenna!
What happened to DB's quality? Upon inspection of the old one, it
seems as though the "glue" that was suppose to be keeping the water out was
not only sparsely applied but was also very brittle. Any movement of the
harness would crack the glue resulting in a potential place for water to
enter the harness.

We have installed several new db-224 recently. This
particular antenna
was inverted and has been in service less than 6 months.
While doing a routine test, I noticed the ref. power was a little
high. The longer the TX was up, the lower the ref. power got; which
typically indicates water in a connector or cable.
We found water in the connector at the center of the antenna. It DID
NOT come through/around the weather seal!
The harness was carefully disassembled. Water (and corrosion) was
found in the molded junction above the center connection.
Has anyone seen this before? Has the quality slipped that much on
the new db-224's?
Any feedback is greatly appreciated!
