If properly tuned, the UT-2700 is a potential competitor of the tinlee.com filter. However, per Winegard, it effects four channels above and below the channel it's tuned to.

However, before buying a filter and the test gear needed to tune it, consider that 'adjacent channel interference' is a bit of a misnomer. A properly tuned, legally operating transmitter is not perfect. It does not transmit 100% of it's RF in the assigned frequency range. Government regulations accommodate the reality that a very small amount of RF will be generated at frequencies outside the channel boundaries. When signals from two transmitters are nearly equal in strength at a receiving location, the very low levels of 'off-channel' emissions may be tolerated by a receiver. But when one signal source is very strong relative to another on an adjacent channel, the strength of 'off-channel' emissions is great enough to interfere with the weaker signal. (It would be cumbersome to to say, "On channel interference generated by an adjacent channel transmitter". But that would be a better description of the problem.)

In your case there is a 30 dB (1000:1 power difference) between the CITY, real CH-44 signal and the WNED, real CH-43 signal. Therefor the 'off-channel' emissions from CITY are 1000 times more significant as a source of interference to the WNED signal.

A perfect filter tuned to CH-44 will control the 'on-channel' signal from CITY but will still pass real CH-43 frequencies, including those generated by sources other than the WNED transmitter.

Your best hope for reception of WNED is to build, tune/adjust an antenna that has little sensitivity in the direction of CITY while having optimum sensitivity in the direction of WNED. A quality bandpass filter tuned to CH-43 may help, but I doubt a filter by itself will provide a reliable reception solution. Success lies in maximizing reception of the RF radiated from WNED while minimizing reception of the RF from CITY, including both the on-channel and off-channel emissions.

So, how would you answer the question posed in post 24 of this thread?
