HDMI Transmitter Receiver

Now I have 3 different sources for the TV signal (Antenna, dish, CD player). Apple TV would be a 4th. Lots of cables to the back of the TV.
But,,,, I'm building a new house and want to put a TV over the fireplace in both the living room and the den (30' apart). My signals from Seattle currently are marginal, though steady. A single splitter and I lose half the stations.
If I use a HDMI transmitter and 2 receivers, can I a: get rid of the wiring mess from the tuners to the TV, b: can I service both TV's without losing signal and c: is there a downside or signal loss at the transmitter or receiver?

laurie in Ladner BC with a DB8e and a 4 ft dish.

I have used Briteview products to send HD wirelessly. Worked well for Bluray too.

Have you tried a pre-amp or distribution amp to resolve the splitter loss?

FTA, Openbox S9, 33” dish, Avenger PLL LNBF. Stab 90HH.
OTA, CM4221HD, 3410 amp, 4 way split, HW-150 PVR

I agree with @Jorgek , a low gain pre-amp can work well if splitting to two TVs. It will overcome line-loss between the antenna and TVs so you'll get a bit more signal headroom and maybe more channels if they are on the fringe.

I've tried 2 different pre-amps (CM7777 and the RCA). In the case of both, putting in the pre-amp lost me more channels than I had without. That was just directly to the CM7000Pal DVR.
I'll put up a second antenna and dish, if necessary, for the second TV, but I will have to plan ahead for the cables to the receivers and hide the cables to the TV's in behind the paneling (or tile, or brickwork) over the fireplaces and into the TV's. I'd just as soon do everything wirelessly.

This question should have been asked in the Home Theatre Corner forum. This forum should be used for discussing issues related to OTA TV. HDMI transmitter/receivers are not OTA TV related.

The OTA Reception Results forum is a good place to post a TV fool in order to help diagnose reception issues in your area and, possibly, find a suitable preamp.

I thought about moving the thread when it was first posted but one of the options is configuring the two TVs differently in a typical OTA application.

Using a higher gain antenna will help with sending OTA to 2 TVs. It would need to have at least 3.5db more gain on all the problem weak channels to maintain reception. A lower gain (than the CM7778) or a variable gain preamp with a higher overload threshold might also work. That may have to be combined with notch filters to reduce overload from strong signals.

There are a number of HDMI transmitters available. They have varying range and reliability but a good transmitter with 2 receivers should work in this situation.

A better option may be to use a DLNA capable TV tuner with 2 smart TVs or DLNA media players. Most smart TVs and media players are DLNA compatible so that's not a big issue. The HDHomerun Extend is DLNA compatible but I don't know how well it will work in this situation. A HTPC with a TV tuner card is another option. Use of a HTPC provides extra possibilities such as OTA TV recording and additional streaming capabilities but setup can sometimes be complicated.
