<p>[QUOTE="DW-77, post: 122280, member: 38055"]Thank you Rick. The CS-4 is up there, doing a pretty good job, pointed at 243deg-M. It also "happens to have" (read: "I scrubbed many radiation patterns to find this one"), a notch at 24deg-M, to lower the level of channel 49. (The idea is to reduce the gap between the strongest and the weakest channel, so that I can add a pre-amp or a distribution amp, if needed.)</p><p>Since most of the channels of interest, in both bands, are in the same direction, I think having a single antenna would make sense and is worth trying (as long as the UHF side of that antenna is at least as good as the CS-4). Should that fail, I can keep the CS-4 and combine it with a VHF only antenna. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile :)" />[/QUOTE]</p><p></p>
