Thank you. I couldn't figure out where the antenna was located when looking at the satellite view.

Most combiners are a splitter used in reverse as a combiner. The insertion loss is very low, average about 0.5 dB. So, the most you can gain by stacking is about 2.5 dB.

However, if the field is...

I think it is possible. You have a very weak CH-25 signal coming from BOTH antennas.
