--------- Forwarded message ---------- From: w4dup@juno.com To: k1vv@tmlp.com Date: Mon, 25 Sep 2000 16:54:33 -0500 Subject: Re: [Force 12 Talk] Weatherproofing 40 mtr switchbox Message-ID: <20000925.165434.-220977.1.w4dup@juno.com> X-Mailer: Juno 4.0.9 MIME-Version: 1.0 Content-Type: text/plain Content-Transfer-Encoding: 7bit I use the RTV quite a low - with some bad experiences on some brands. Unfortunately I can't identify the bad ones because I wasn't aware of the dammage until years later when I took some coax connectors loose. I found some bad chaulky looking corrosion on the center pin of my PL259s. I quit using Silicone (RTV) until I found others with NO PROBLEMS. I've had no trouble with Dow Corning 732 RTV Sealant. Generally speaking if you smell STRONG acetic acid (vinegar smell) don't use it. As for weather/UV dammage I'm having no problems with the clear and it's used up the tower. As far as coax connector sealing, a good grade of black electric tape wrapped and overlapping starting from the bottom, is hard to beat and lasts a long time. 73 de Sandy W4DUP On Mon, 25 Sep 2000 16:45:35 -0400 "BobD" <k1vv@tmlp.com> writes: > that could be true ..different mfg ... we have always used GE.. > .. as > for outgassing causing damage we have not experienced that ... or we > never > noticed it . and we have used GE silicon in all kinds of adhesive > and > sealing applications ... interior and in the weather .... what was > the type > of damage is done by the outgassing ?? any ACTUAL experiences?? > K1VV > > > Rome wasn't burned in a day !!.. > > > l Message ----- > From: "Doug Charette" <dougc@kaweahnb.com> > To: <force12talk@qth.com> > Sent: Monday, September 25, 2000 3:14 PM > Subject: RE: [Force 12 Talk] Weatherproofing 40 mtr switchbox > > > > I guess it shows to go you that different people have different > experiences. > > I have used the semi-clear for years with great results.
