2 antennas 2 preamps 1 output to tv ?
 

What do I need to pull this off .
Wanting to add another 91xg as well as a 7777 preamp for a total of 2 antennas and 2 preamps . I assume all I will need is a splitter right before I go into the tv ?

I appreciate all the help I received last time . The 91XG was just the ticket.

Thanks

I am assuming the antennas are aimed in different directions, receiving different stations. (If you are attempting to gang them, to make them into a single antenna, take a look at this information on antenna stacking.)

You can try a reversed 2-way splitter... it's cheap and easy. If it doesn't perform the way you expect, it's easy to back up and start again.

However, there is a reason CATV head-ends have thousands of dollars per channel worth of equipment installed to receive, filter, process and often shift the frequencies. (But if you can get a $6 splitter to work, great.)

Here's what works for me. (Not a one size fits all solution.)

Many use an A/B switch of some type.

I actually am using a Homerun Hd but it is the model with the single tuner.
I may buy an additional tuner that has the 2 inputs and use both tuners.
The antennas will be pointing in different directions.
