Combining two identical antennas
My quest to improve reception of WVNY-DT on VHF 13 continues...
Is-it better to put a balun on each antenna, then join them together by identical coax length to a 2-way splitter used in reverse or to connect their feed point with 300 ohm twin lead and use a single balun in the middle?
- Antenna 1: homemade Yagi, 10 elements for VHF 13.
- Antenna 2: 10y13s
I tested each antenna individually, each one gives about 42% signal on WVNY-DT
I connected them with the first method, putting them side by side, pointing to the same direction and spread about 2m apart, the signal seems to improve to 44% when combined. I also tried reversing the polarity on one of the balun but it did not change anything.
I also tried stacking them one above another, with about 1m apart (space limited in the attic), the combined signal is worse, even if I reverse one of the polarity.
So before I go out and buy twinlead wires, I would like to get some advice
