My experience and those of a lot of guys I used to play with on 2 meter (144.1 MHz) SSB found that stacking vertically gave them more range than a long boom yagi when they were restricted to no more than roof top mounting (not on a 50 ft tower, etc).&nbsp; We always assumed it pointed more of the signal at the horizon, which my stacked YA-1713's appear to prove out as well pointed at Jacksonville.&nbsp; I do wish my YA-1713's though were about twice as long.[/QUOTE]
