21. [TowerTalk] PL-259 Going Open? (score: 1)
Author: Kim Elmore <cw_de_n5op@sbcglobal.net>

I'm not sure Towertalk is the right forum, but here goes: I'm using PL-259s outside to connect transmission lines (Belden 9913) that run up the tower to my antennas to the underground lines that run

I truly appreciate all the responses! The 9913 is not wet inside -- I checked this the first time it happened and it was dry behind the connector that I cut off. I won't get any water ingress into my

As a bit of additional info, I haven't direct-buried any 9913: i's all in conduit. That said, there's no guarantee that the conduit has remained perfectly dry. That said, I have seen no evidence what

Here's what I know about it: http://nepp.nasa.gov/WHISKER/index.html What I'd originally heard was that tin whiskers grew from non-lead containing solder. But this appears to not be the typical case,

That wasn't Peter, it was me. Peter is innocent! Yes, radiational heating was ignored in my analysis and that can heat the coax to very high temperatures without some sort of ventilation. I'd guess t

I've wondered about this, too. Yet, I have another connector that has been fine all this time, used on the same length of coax and has not yet given me any trouble. If it fails in the same way, I'll

I've been shunt-feeding my tower for awhile now using an L-network and a motor-drive to adjust a vacuum variable. Until recently, all has been just hunky-dory. However, last night it appeared that my

I'll double check the transmission line tomorrow. Surprisingly, no water got into the PL-259 and it was dry when I removed it. The tower is an HDBX-48 so it doesn't "shake" very well.. While I was do

All I have is a Fluke 79 multimeter. It will read capacitance, but the lowest it goes is a nF range. At max capacitance, this vacuum variable will be at about 0.5 nF. I've found that this meter is pr
