 ```It would be easier to just feed one vertical with a random length of 50 ohm coax and make the other vertical a parasitic reflector. John KK9A To: towertalk@contesting.com Subject: [TowerTalk] Phased verticals one direction From: Bob Ad5vj Date: Wed, 02 May 2012 10:44:20 -0500 My first Rodeo on phasing, need confirmation please. I am working on 2 34' phased verticals spaced 34' for 40 meters pointing in a NE/SW line. SW ant we call #1 NE ant we call #2 I am wanting ONLY NE direction. Using my MFJ-259B I have determined the length of coax I have (RG-11) to measure 106.2' to the fault. Physically measuring the coax it comes to exactly 72'. Dividing 72/106.2 I get a measured velocity factor of .6779 according to the MFJ manual. (468/7.150)/2 =32.7' per 1/4 wave 32.7' X 3 = 98.1818 for 3/4 wavelength 98.1818 X .6779 = 66.55' So this should be the physically measured coax length for the 3/4 wavelength going to the #1 vertical. Then I do the same for a 3/4 coax wavelength from #1 to #2 antenna. Does that sound right? _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk ```
