John,

I don't understand the "draining" technique just by looking at the sketch of the antenna but know from experience that water sealing sometimes result in accumulation of water there it doesn't belong. That's what drain holes are for.

A tips though, I usually flood my connectors with VASELINE just to make sure there is no room for water. I've seen the phone companies do that to prevent corrosion on their connectors and also worked with outdoors cables that have VASELINE inside. Very, very sticky but seems to do the job. A thin layer of it doesn't seem to cause connection problems as you might think. I don't know if the connecting part is pressing through it or if a thin, thin layer is conduction. I have heard both theories.

I wish that I understood this but from the drawing I cannot see how
waterproofing the connector causes harm to the antenna. I certainly do not
trust N connectors to be water tight and from the drawing it does not look
like the connector is out of the elements.

Great info, Steve. Couple of questions:

2. A little OT, but regarding your advice to weatherproof N connectors, I've
always done that, but I'm about to install a Hustler G7-144 2m antenna on
top of my tower and the instructions explicitly say not to apply any tape or
weatherproofing to the N connector because the antenna is designed to shed
water around the connector, and sealing this area will cause the antenna
retain water. Instructions here:

https://static.dxengineering.com/global/images/instructions/hsr-g7-144.pdf).

Living in New England I'm skeptical about this, especially for an antenna
that's 115 feet in the air. What would be your (or any one else out there)
advice? Should I obey the K7LXC prime directive -- "Always follow the
manufacturer's instructions" -- or ignore the instructions and weatherproof
the connector?

73, Dick WC1M
