![]() "David" wrote in message ... Make Folded Dipoles and use a CATV balun backwards at the feedpoint. Then you can use plain old RG-6 and F-Splitters. Not only is this incredibly cheap, the entire antenna system is at DC ground*. Caution, do not use Baluns with little capacitor inside. *Use an F Grounding Block where the coax enters the house. And a drip loop. http://members.shaw.ca/weskyscan/ima...ldedDipole.gif There is a potential problem here in that many, many baluns and splitters intended for CATV have very poor performance at HF- i.e. balance is poor, insertion loss can be well above theV/U values. For the splitters, port to port isolation can be very poor, loss higher than may be acceptable. Finally, I have yet to see a CATV Balun that is acceptable for out door use. I wouldn't count on the system being at DC potential either- there are several methods for creating a 4:1 balun- and seeing as how the wire used in these baluns is smaller than #36 gauge- it wouldn't take much to fry it anyway. Wouldn't it be much simpler to build a classic dipole from single conductor wire, place several clamp on #43 cores at the dipole to feedline transition and forget about the CATV stuff and fragile twinlead??
