Hi - I'm looking for a bit of advice on aerials that will best reject signals coming from the rear, and the opposite polarisation.
The aerial will be mounted horizontally and pointing towards Sutton Coldfield. Until the 700MHz frequency changes earlier this year, our current aerial could not receive COM7, COM8 or the Local mux due to co-channel interference from Mendip (also using UHF33, 35 and 51 for these muxes). Mendip is almost 180 degrees relative to Sutton Coldfield, so its signals were hitting the rear of the aerial and knocking out Sutton Coldfield.
I can now receive COM7 and COM8 as they are on different frequencies to Mendip, but when Mendip's frequencies change to 55 and 56 next year, I expect to lose these with the current aerial. I'd also like to receive the Local mux (on UHF48) too - this briefly appeared but was lost after Bromsgrove's ARQB moved to channel 48 (vertically polarised). Bromsgrove is almost in-line with Sutton Coldfield from my location (5degrees difference).
Am I best going for a longer aerial with more elements, a high gain figure, and/or a high front-to-back ratio? I've been looking at the following:
Fracarro Omega 8
Gain 16
Front-to-back 32
Beam width 22
Antiference XG10
Gain 14.9
Front-to-back 26
Beam width 16
Antiference XT48F
Gain 16
Front-to-back 29
Beam width 26
Antiference TCX18T
Gain 15.7
Front-to-back 22
Beam width 19
Vision V1048LF
Gain 13.8
Front-to-back 26
Beam width 15
Triax 108451
Gain 14.5
Front-to-back 25
Beam width 15
Any suggestions gratefully received!
