By the way, you still must seal the connectors with a good tape like Scotch 33 first, then coat at least two coats with Scotchkoat. Sorry for the 2nd email, just wanted to clarify.

Hello All, >From what I have seen the quality is the same but I have been preaching on this board and others you can’t 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 don’t 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.

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?
