I recently built a jpole for 11meter from 300ohm twinlead and 12g copper wire. Radio with 30 watts had a 1.3 swr and about 1.7swr on 10 meter, and have made many dx contacts. 1/2wave`s are a bit long on 11/10 meter about (27ft).
BUT curiosity wants to know if anyone has built a 1/4wave jpole .Or can someone help with calculations to build such, like radiating length, stub length, and feedpoint locations? Like i said" curious about 1/4wave" (about 14)ft
Any thoughts? Thanks
