Hi guys,

I am having an issue regarding my tv signal on a 4th TV in my house. Apologies for the paint art but it's the best I can do. To put it as basic as possible - I live beside my grandparents and they have a better signal than I do from their aerial due to tree obstructions around my house. What we have done is ran aerial cables between my house and their house underground so I could pickup channels also. This works perfectly on my main TV however on my bedroom tv (TV4 on graph), I can only really get a watchable picture now and again (generally a good calm day when signal is probably at it's strongest). I get a strong signal at TV1, TV2 and TV3 - why can I not get a strong signal at TV4 considering it is wired up the exact same way as TV3.

I have tried an attenuator but that had no effect on the signal.

If there any suggestions please drop them below, thanks!

*In the image below the circles represent where signal splits with a passive splitter.

*I believer there is also a booster after the masthead amp in the attic of House A.

Would a small booster work in House B to help push the signal along to TV4?

I’m installing a new ground rod because my old one is no longer good and is inside the house rusted and all. What is the best way for me to ground my roof top antenna to the new rod? Also what’s the best way to ground the coaxial cable outside for electrical interference?

Trying to figure out why I have no signal. I know nothing about this stuff.

Lightning/power surge destroyed my indoor amplifier I think, which is a permacolor 10g212 by antennacraft. I plug it in, and the LED turns on then fades out over like 5 seconds, then if I unplug and plug it in again the light just doesn't come on unless I let it sit a while. I have no idea what the pre-amp is but I see one on the mast. I have a 40 foot tower I dont want to mess with if i don't have to.

There is nothing i can find in the house along the coax that gives power to the pre-amp. Is it possible the permacolor 10g212 did this. I bought a cimple tv amplifier hoping to replace the permacolor but i still have no signal, either the preamp is also fried or it's not getting power, or the coax is bad, or the thing that attaches to the antenna from the pre-amp is bad.

I don't know if the tower took a direct lightning strike but lightning did strike very close, something popped in the basement or just outside, AC temporarily didn't work but now it does, I was only worried about the AC but come to find the i get no signal on my TV now.

The tower has been hit before and it never messed with the TV, did fry my internet antenna though (thankfully no longer have to use wireless internet anymore)

Any help appreciated, i don't want to climb or lower the tower (its hinged but it'd be a hassle, although if the thing attached to the antenna itself is bad lowering the tower will be my only option

Has anyone else noticed the audio and video getting out of sync on OTA broadcasts? My local CBS affiliate is about one second out of sync on ATSC3, but not so bad on ATSC1. The ABC and PBS affiliates are still pretty good. The NBC affiliate was pretty good, but lately has gotten worse. I have noticed this both through my Zapperbox, and directly from antenna ton two different LG TVs. This is while watching live local news.

Side note: When ATSC1 first started, our PBS affiliate was out of sync, but then got better.

Can anyone figure this one out? My NVR system and POe cameras cause my VHF channels to drop. The system is plugged in and setup in a whole different building 70ft away from the antenna or coaxial wires but each poe Ethernet cable I plug in to the NVR causes my VHF signal to drop. Once I have 4 POE cameras plugged in I lose my VHF channels. Is there anything I can do about this? I’ve messed around with this and have definitely pinpointed it to this system and so far have found no solution. Could it be the Ethernet cables, the power cord powering the NVR?

It is a Anpiz POE camera setup with there NVR and own cameras.

I am about 40 miles south west of DC and getting a great signal for WPHL17 in Philly.. Conditions and bounce working in my favor. About 160+ miles to their towers.

I know SS means signal strength but what does “Last MER” mean?
