FWIW...I thought that I'd pass on my operational impressions of my F12-SigmaV vertical, now that I've run it through the "CC&R-paces" for the past 30 days or so. Last month, I installed the F12-SigV vertically in my 9'2"-peaked attic (nice fit!) -- I removed the plastic cover from the center assembly to facilitate easier 'coil-fiddling' and such, and removed the mounting insulator from the bottom T-bar -- cabling dresses nicely away (for about 12' horizontally) from the center-assembly (at a 90 degree angle) as well. I can report extremely nice results with my K2 barefoot (5w) on CW, and also driving a small solid-state 50w P.E.P. amp for phone use. Just for giggles, the installation location of the vertical is, coincidentally, perfectly centered just above (about 12-18 inches) the area that the metal garage door occupies when it is opened (up). I have used the F12-SV on 20-17-15-12 & 10m with the door down, and with the door up. I can report that with the door down, I have no 'problems' on any band, under any band conditions, When the door is raised (up/opened), I found that on 12m & 10m that operation is somewhat "enhanced"...that is, reception of stations using vertical polarization seem to be more stable in signal strength and less immediate fade. Also, I can report no real skewing of the antenna band tuning either. Granted, I do feel kind of silly raising the garage door to work DX on 12 & 10, but what heck! ~;?)} I also suspended it horizontally in the attic -- nice results too -- comparatively speaking, I prefer the vertical orientation of the antenna though. While I do not have a problem paying-the-price for a superior-performing-product, such as a Force 12 antenna, I must (respectfully) comment that the presently used plastic cover for the F12-SV center assembly seems somewhat cheap & flimsy, along with the poor soldering quality of the center assembly joints and the band-selector switch assembly. I have since resoldered all of the cold-joints, I don't expect to have any problems with them. Perhaps the one that I own was built on a Monday...I don't know. Happy Holidays and Good DX! 73!
