- Got a new Beverage antenna up and getting the termination resistor(s) ready. to install? The resistance is spot on, now to keep it dry, you put it in some heat shrink. There, now for a re-check of th

- Anyone else found a lowering of resistance after heat shrinking terminations after cool down? 73 Bruce-K1FZ You may have some of that somewhat conductive heat shrink tubing. Good idea to check the gl

- Depends on the method used to provide the conductivity. If it's carbon black filled, the shrinking is goin g to push the molecules of the carbon black closer together and that results in a net decrea

- Heat shrink squeezes resistor. Squeezing a carbon composition resistor will decrease its resistance. Film and ceramic resistors much less affected. Remember when we were kids and played with telephon

- Like Tom, I install my carbon composition Beverage termination resistors fully exposed to the weather. I measure them annually and over a 20 year period just a few have changed resistance outside of

- I've covered my resistors and solder joints with GE Silicone II sealant and have never had a problem. The curing does not impact solder joints and I've used this product for some 20+ years. I can't m
