Massive boost

Received the CM-3424 Booster 4 last evening (05/24/2024), after trying a different manufacturer's brand. What a massive difference. On re-scan and with everything else being exactly the same, I went from 392 signals being found previously to 462 (OTA and Cable) on my Samsung TV. The quality on all channels is crystal 'break up or pixelation anywhere). This was money well spent. The product feel substantial in hand and is well-built. Had I known I could receive this type of signal quality, I'd have quit cable/sattelite TV years ago.

Fingers crossed that this splitter lasts!

I have recently replaced a 4 port Antronics powered splitter with Channel Master. I have had 2 Antronics devices in as many years, but they stop working about 1 year in. I have them grounded to the house ground with a heavy gauge copper wire, also have them plugged into a surge protector, but they failed. Hoping that this new Channel Master device lasts longer. So far so good.

Quality and Value

Just received and installed this powered splitter, having 4 televisions hooked up to one antenna the signal was dropping out on 3 of the channels .I tried some other powered and non powered splitters which were worthless .This gave me a signal gain across all channels as well as stable signal. I am very happy with this purchase and the quality of the product. Do not hesitate to buy this ,you will not be sorry ,I just wish I would have gotten this before trying all the others .GREAT PRODUCT ! Fast free shipping !
