All - I have an after market TV tuner, it has 4 inputs for the diversity antenna(s). I also have a the diversity antenna set with all of the correct 1/8" mono plugs.

Can anyone explain how diversity antennas work? The instructions with the tuner and antennas are cryptic. From what I have read via advertisements and product descriptions, diversity antenna setups are supposed to be able to pick up the best signal from one or the antennas.

With 4 inputs, do you have to use all four?

Are each input 75 ohm or 50 ohm impedence?

Any help, webpage URL or anything describing mobile TV antennas would be a great help.


Thanks,

If you go to electronic store or eBay, you'll see what's called diversity antenna. They are either 2 or 4 channels (coresponding to number of plug). The plug is a standard 8mm.

The 4 channels one works better than the 2 channels. Mount it in the rear windows, and run the 4 wire to the tuner box. The tuner box will automatically tune to the channel with the strongest signal while you're watching TV.

However, as you drive, regardless of antenna and tuner type, signal will be degraded significanlty. It's just the nature of TV signal.
