1. [TenTec] balun noise? (score: 1): Author: "Denton" <denton@oregontrail.net>; Date: Thu, 22 Nov 2007 23:18:38 -0800; Not really a ten tec question...but this little group seems to be particularly knowledgable... I am tinkering with an 80 meter inverted L antenna, and I noticed that when I hook up any kind of balun; /archives//html/TenTec/2007-11/msg00458.html (8,619 bytes)

This is an unbalanced antenna. I suggest you follow the design of the 160m version; /archives//html/TenTec/2007-11/msg00466.html (10,898 bytes)

This is currently just a recieving antenna, but found my configuration just worked out to resonance on 3.60 mhz.

These work great, cost little and can handle more power than you can generate. Do note, RG-213 is the coax to use. Don't use the foam stuff.

8. Re: [TenTec] balun noise? (score: 1): Author: chip_brown@isp.com; Date: Sat, 24 Nov 2007 08:27:17 -0500 (EST); This works Great. I used about 50' feet of RG-213 (a piece I had around with a connector on one end) and about 24" of 3" PVC. Works fine down to 160m.
