Need help. 140 degree offsetting sources.
Hi all, new to the forum, I've tried to do as much research as I could using this forum before posting, but am on information overload!
I live about halfway between two cities (Springfield, MA and Hartford, CT) and would like to pick up the stations from both. I'm mostly interested in real channel 34 (S), 11 (NNE), 36 (S), 26 (NNE), and 22 (NNE), but obviously would like as many as I can. http://www.tvfool.com/?option=com_wr...9038fb062e75be Currently, I have two directional yagi antennas in my attic attached the same pole with a passive combiner and no amp. I know, not ideal, but it seems to 'mostly' work. The signal can get choppy and I get severely frustrated. I'm familiar that two signals could be out of phase and causing the interruptions. I've done a bit of research and learned that most of this forum tends to stay away from omnidirectional antennas, and I would not want a rotor or A/B switch. What would my best option be? Considering the stations I want clear are fairly close, would an omni work well? I've also read of bi-directional antennas like the Clearstream 4MAX which works best at 180 degrees opposite of each other, but if I turned it 20 degrees off direction, would it work well enough for the 140 degree offset? Another thought would be to separate my current antennas and maybe put something to block the opposing signal in between, like some plywood covered in aluminum foil or something. Any input will be appreciated! |

My usual suggestion for maximized reception with a plot like that would be a DB4e with the reflectors removed plus a VHF dipole.
For something out-of-a-retail-box, the C2MAX or C2V (reflectorless) would be my first choice, followed closely by the C4MAX or a C4V (reflectorless). The beamwidth of the C4/C4MAX is right on the edge of predictiability. Many times, choppiness as you described is caused by factors such as trees shredding the signals. Being in an attic will exacerbate the problem by adding additional multi-path. |
I agree with ADTech. The CS2MAX or the C2V without reflector and with the VHF dipole, has the wide bi-directional 70 degree beamwidth that might work for you.

Thanks for all of your feedback!
I wound up going with the Clearstream 2Max. I mounted it outside last night and currently getting much better reception than before. It seems to pick up both directions perfectly. |
Thanks for updating your report. Always good to hear of a successful install!
Best of luck! |
