[Amps] Silicone chimneys

[Dennis W0JX]

For external anode tubes, I use aircraft grade red silicone baffle material. It comes in 9 foot rolls x 3 inches wide and is 1/8 in thick. It can handle up to 550 degrees F. Current price is $32.95 per roll from suppliers like Wag Aero, Chief Aircraft, etc.  Sometimes you can buy it by the foot at a local aircraft repair station.
   
  It works great for my 8877 amps. I don't glue it but make a tight friction fit over the anode and staple it together and cover the staples with high temperature tape.
