When I lived in Hampton Roads (and was in the Nav) I eventually came on
to the following algorithm:
2 layers of good electrical tape
2 layers of coax seal
2 more layers of good electrical tape, each overlapping the under layer.
When I retired from the Navy and took the antennas down, connectors that
had been in the air for 15 years looked brand new. An additional
bennie, if I had to open one up, just a slit with a knife and I could
peel the layers back & get access to the connector. When done, just
press back into place and cover with 2 more layers of good tape.
Worked great for me.
Good luck & 73,
Jim

I am not a fan of COAX Seal, it tends to migrate into the connector.
In the Hampton Roads area, a NAVY town, we use the old NAVY way:
* Light application of high great Silicon
* Double sided electrical tape rap
* Electrical tape rap
* Spray lacquer over
* Nylon tie on each end
Great seal!

Well I look my antennas over each year but they have always been
relatively easy to get at even when they were on a glen martin tower
on the roof, I could see every other year if it is a major
undertaking but based on his call he is in New York, to think you can
put a antenna up and ignore it for years in a area with snow and
freezing temps stretches reason.
I'm also a fan of coax seal and some sort of coating on the
elements, When I look my antennas over I'm checking for loose bolts
and UV damage to plastic parts and coax, out on the west coast it is
the Sun and heat that is the thing to worry about.

I'm neutral on this topic, but I was curious if the M2 Manual mentioned
anything about maintenance. Here are the instructions:

There is no mention of maintenance. Of course, it would be a good idea
to check things out regularly. But, depending on where the antenna is
installed, it could be quite difficult to get to it once it's put
up. I can't think
of anyone that actually does yearly maintenance on their antennas.
My rule
of thumb is to anticipate what problems could occur and do what's
necessary
to avoid them during the initial installation. I always use
Coax-Seal and spray
the heck out of everything with clear Rustoleum.

Might I ask what sort of preventative maintenance did you perform
each year?

Purchased a M2 436CP30. Had a failure of the switching block in
less than 5
years. White plastic cracked and allowed water to ingress to the
switcher.
Customer service?? No return call.
Pics on request.
