View Full Version : Multiple Silver Sensors & outdoor mounting hardware

Pardon my ignorance, but can you combine 2 or even 3 Silver Sensors together?

Thru trial and error of several antenna's I have found the Silver Sensor to be far better than any other antenna. I have mine connected via an amplifier and I get 100% signal on a station I was getting only 50% before on one of the highly recommended bow-tie antennas.

2 of our stations are on the same tower. Another 2 are on towers very near each other but a few degrees from the other 2's tower. The 5th station is completely in the opposite direction. I get a great signal on CBS, ABC and FOX, and marginal on NBC with one element of the antenna stuck under the shingle of the roof. (I can get a better singal on NBC, but when I move it I lose the other stations).
If I point the antenna 180 degrees from where it was I get the UPN station but lose all the others. (When PBS fires up later this year it will be yet in a 3rd direction.)

My long winded question here is can I get 2 other Silver Sensors and combine the signal somehow into 1 lead to the tv and have it work for all stations?

Or is the best best some sort of rotator.

Thanks! :santa:

Bow antennas tend to be directional in nature, so that might be why you did not get the expected results. Since digital signals are especially sensitive to multipath corruption. Combining a signal from multiple antennas into one feed line can create more headaches that you want. By connecting several antennas together you are essentially combining interference and multipath corruption from each antenna. A filter for each antenna would be required to pass the frequency (channel) that each antenna was required to receive.

I would stay with the time tested antenna rotor or perhaps and A/B switch, but if you do prefer to go this route a device called an antenna combiner can be used. This device will take two signals from two different antennas and join them into one signal cable. One that comes to mind is the Channel Master JoinTenna . This device can be ordered with traps that will only allow a narrow range of frequencies to pass thus eliminating some multipath/interference problems from each antenna.

IMO... rather than wasting effort and $$, why not just get a 'traditional' antenna and a rotor?

By the time you buy 2 or 3 more SS's, combiners and coax/connectors, you could do it properly for almost the same cost (and probably have better results).

Just my opinion.

I have to strongly agree with the previous two posts.

The multipath issues will defeat the purpose for having HD in the first place, clear crisp PQ.
