Can I have the best of both worlds, F-Type connection and wireless?

There have been discussions here on what kind of antenna to use to transmit - give it a search.

Combiner manual says 17 dB insertion loss, so you need a 17 dB amplifier following it to get back to the modulator output level. It also needs to be able to handle the desired signal level without crossmodulation, so you need a 20 dB gain distribution amp designed for the high signal level input; a 20 dB antenna distribution preamp may have problems.

I found a boost from a leaf antenna that I'm not using. From the combiner, I output to this boost, then this boost goes into the splitter. The antenna that's attached to this splitter works better now. However, I get these ghost bars going from left to right. If it only happens on the wireless sets, that would be okay, but now all the tvs with the direct connection are getting this left to right scrolling bars too.

But I went back to my original set-up without the boost, and I started modulating to some UHF channels, and the wireless reception did work better for some of these UHF channels. But still, not the same quality as direct connect. BTW, when I'm doing these testings, the antenna and the wireless sets are in the same room, maybe just a foot away, and I still can't achieve a clear picture like I would with a direct connect.

This is cross-modulation, what you would expect from using an ampifier meant for weak antenna signal levels to amplify a group of higher level signals. You need a cable-system amplifier designed to work at high levels.

Aren't we dealing with broadcast frequencies here

Cable frequencies include broadcast frequencies.

What would be more ideal, putting an amp before the combiner or after? If before, then I would need to find an amp combiner? Is there such a thing? LOL!

What are cable system amps? Like any old school blonder tongue amplifier? I searched ebay for Blonder Tongue Amps and most are just one in, one out. Can you tell me which of these search results fits my need?

Good news! I just realized something... since my wired pictures are fine, I did not need to put the boost between splitter and combiner, which was causing this cross-modulation even with the wired picture.

I just tried placing the boost between the antenna and one of the outputs on the splitter. But doing this, the boost needed to be used backwards by using a f-type coupler. Wireless reception is much better now with some ghost bars, depending on channel, it can go up and down or left and right, but the picture is clear. And this time, the wired tvs are not effected, they are still crystal clear.

I'm still going to buy some of those blonder tongue amps, just to see how all this looks with better equipment.
