Steve, A 500 kc split shouldn't be a problem. You will need 4 filters in each leg for 100W TPO. I did use a different method rather than making a box to solder to the top of the heliax. Details here.. as well as links to additional info. <http://65.173.252.46/Six_Meter_Heliax_and_Helical_Duplexer_info/6m_duplexer _page.htm> They are not difficult to build, or tune. Good luck.

The split here is only 500Kc, so it maybe a problem. Not having any decent test gear, ie, spectrum analyser etc I may find it a problem. I have looked at a commercial duplexer, but at 1200 UKP( about $2000), it is a definate no :-). If the worst comes to the worst I may use 2 ants, hope I can get enough space between them. 73 Steve ----- Original Message ----- From: "n9eerptr" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Friday, July 08, 2005 12:06 AM Subject: [Repeater-Builder] Re: Duplexer > Steve, > > You might have this info.
