[Elecraft] Remoting KAT500 to base of antenna

[David Anderson]

Just a wee note about the fitting of those nice Gore vents. It is important to have a suitably sized vent or vents for the volume of box and the type of equipment inside it, and Gore can calculate that for you. 

For a simple small box for a masthead preamp it is OK to just choose one of the eBay or Farnell/CPC ones that you can buy in one off quantities, but for a larger enclosure with a big investment you want to do it right and the manufacturers will be happy to oblige. I went through Gore in the UK to get my info, and they even sent me free samples as their minimum order was for 100 off.

Unlike drain holes which would be in the bottom of the box, Gore vents are mounted on the vertical wall of the box.
