My question is -- is it worthwhile to install 1.5 megohm resis; /archives//html/Towertalk/2003-01/msg00447.html (7,943 bytes)
2. [TowerTalk] static drainage (score: 1): Author: ccc@space.mit.edu (Chuck Counselman); Date: Mon Jan 27 08:58:49 2003; Yes, very much so! An antenna (or part of an antenna, such as one-half of a dipole connected to the center-conductor of a coaxial feedline) left floating very easily acquires a (literally) staggering; /archives//html/Towertalk/2003-01/msg00448.html (8,002 bytes)

If you get a nearby lightning strike it is possible to blow the resistor and never know it--then you no longer have st; /archives//html/Towertalk/2003-01/msg00449.html (8,835 bytes)

With such protectors (ICE and Polyphaser both have DC grounded models) there is no need for any other form of static drain. Plus, I've been told that with continuous static drain, it makes yo; /archives//html/Towertalk/2003-01/msg00453.html (8,918 bytes)

Given that, couldn't I simply shunt an RF choke to ground inside the relay box at its outpu; /archives//html/Towertalk/2003-01/msg00455.html (8,761 bytes)
