1. Topband: Term. resistance and location of K9AY (score: 1): Author: <armin.ficza@nokia.com>; Date: Fri, 8 Sep 2006 12:11:26 +1200; Hi, I have some questions, First of can I use metal or carbon film resistors, or it has to be composite type? ( same as beverages) My second question is about the location. My problem is, that my QTH; /archives//html/Topband/2006-09/msg00005.html (6,813 bytes)
2. Topband: Hints for 160m TX antenna (score: 1): Author: <armin.ficza@nokia.com>; Date: Mon, 11 Sep 2006 09:45:46 +1200; Could you give some hints for limited space and stealth antenna? I have abt. 45ft tall supports (tree) and 90 ft horizontal space. Maybe linear loaded inV V? Or vertical dipole with capacity hats on; /archives//html/Topband/2006-09/msg00019.html (6,878 bytes)
3. Topband: Linear loaded vertical H (score: 1): Author: <armin.ficza@nokia.com>; Date: Mon, 11 Sep 2006 11:23:17 +1200; Beginners question: I modelled a vertical H antenna with folded legs, 12m height and 34m wide. It looks fine from gain point of view and max radiation at 20 degrees. The only problem is, that if I fe; /archives//html/Topband/2006-09/msg00020.html (6,910 bytes)

7. Re: Topband: RG-6 Coaxial Cable... (score: 1): Author: <armin.ficza@nokia.com>; Date: Sat, 16 Sep 2006 07:53:03 +1200; I am just wondering, how do you handle the SWR issue with RG6? It is 75 Ohm cable. For receiving only antennas, SWR isnt an issue? I don't think so. 73, Armin, ZL1KMN ________________________________; /archives//html/Topband/2006-09/msg00060.html (8,353 bytes)
8. Re: Topband: K9AY LOOP (score: 1): Author: <armin.ficza@nokia.com>; Date: Mon, 25 Sep 2006 08:30:04 +1200; HI Bob, Twinmlead isnt a good solution. IT will pick up a lot of noise, thus it will be unusable. 73, Armin ZL1KMN _______________________________________________ Topband mailing list Topband@contest; /archives//html/Topband/2006-09/msg00098.html (6,848 bytes)
