Tom the name comes from the inductance used on Yagi's as a Hairpin match simply because it looks like one. When used on a vertical it simply goes from the bottom of the insulated conductor to ground. Are you using a PI- L network in the PA for a start. I would worry about harmonic content as a separate issue to the best way to configure the L or T. Again a simple coax stub could fix the problem. 73 Clive GM3POI

Using capacitor matching forms a low pass network which will reduce harmonic radiation. The inductor method forms a high pass L-network. BTW, why is it called a 'hairpin' inductor? Looks nothing like a hairpin, or does it? 73, Tom G3OLB _________________ Topband Reflector Archives - http://www.contesting.com/_topband --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus _________________ Topband Reflector Archives - http://www.contesting.com/_topband
