Here is a link to Chuck's site that shows one, http://www.philcorepairbench.com/mystery/40-6112.htm
Basically it is designed to improve the signal gain performance over a standard wire antenna. It has two leads of twisted wire that connect to a transformer that connect a coax type cable the runs into your house. It has glass standoffs so the antenna is isolated from trees poles or whatever you connect it to and the return line has standoffs also. There is a ceramic block that you connect the outside lead to, then a lead that connects to a good "earth" ground and a terminal for the house lead. The block is set up that if lightning strikes the antenna that it shorts before the power spike gets to your radio and does any damage. Most electric fences have lightning arrestors on them also so if you make your own outside antenna you can go to a TSC store and buy one but the All-wave antennas pop up on ebay quite often and I have not paid more than $26 for either of mine including shipping. Here is a link to one for more modern radio/tv equip but the principle is the same, http://www.rflinx.com/Cables-Connectors-...restor.htm
