I have 2 units one at the antenna and and another that connects to the cable outlets to the TVs ...very little problems prior to that I was having the same problem...also check on line for best antenna direction(use compass for station signals) you'll need two people ...one for antenna adjustment second person to view best reception for your channels use cell phone ---walkie talkies---loud voice...better known as a " big mouth"...its trial and error...you'll eventually set it right...its take time ....so be patient...once you locate the right spot you will know....if then the is some disturbance...then just tweak it....good luck Just nto let you know my is working great...I have 5 tvs **Q: Can i use this preamplifier (cm-7777hd) and the ultra mini 2 distribution amplifier (cm-3412) same time?** A: Yes you can! That is what I had to do to get a strong signal to all of my TVs. I would buy an extended warranty with both items. The warranty sucks and mine died right after it was over. Now I have a new one with a Square Trade warranty just in case this one dies early too. **Q: Can I use this on a antenna that’s already amplified?** A: Yes, but you run the risk of overloading the front end of your TV receiver. That could lead to damage or a poor picture. If your TV can display the received signal strength from your antenna, check the signal strength before installing the CM-7777HD. If you see two or three bars out of 5, you can try the CM=7777HD on low amplification and immediately test the received signal strength again. If you see 3 or 4 bars you are good. If you see 5 bars you may be ok. I have my CM-7777HD installed at the antenna. I use a splitter to serve two TVs and have a second amplifier installed on each leg after the splitter. Hope this helps. **Q: This pre amp keeps loosing power green led shuts off no signal unplug power insertion plug back in works 10 to 20 minutes this is a new unit anyone ha** A: Return it. I purchased one along with a Channel Master 100 directional outdoor tv antenna long range CM3020, and struggled with it for a week all the while communicating with channel master. Still received only PBS station lost 29 channels. Finally removed it and plugged old radio shack preamp and tada! Recovered 29 channels. ## Frequently Bought Together - Channel Master Amplify - Adjustable Gain TV Antenna Pre-Amplifier, Built-in LTE Filter, 17-30dB Gain, Compatible with Non-Amplified TV Antennas, Increases Signal Strength, Indoor/Outdoor - Channel Master Splitter 2 | 2-Way Splitter Distributes Digital HDTV Antenna Signal to 2 TVs, One Input and Two Outputs, Power Passing for Preamplifiers and Boosters, Low-Loss Design, Indoor/Outdoor - Channel Master LTE/5G Filter – Reduces Pixelation & Signal Issues from LTE, 4G, 5G Interference, Indoor/Outdoor Use, Built-in O-Ring for Weather Protection, Enhances OTA Digital HDTV Signal Quality --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.ke/products/31222491-channel-master-amplify-adjustable-gain-tv-antenna-pre-amplifier-built](https://www.desertcart.co.ke/products/31222491-channel-master-amplify-adjustable-gain-tv-antenna-pre-amplifier-built) --- *Product available on Desertcart Kenya* *Store origin: KE* *Last updated: 2026-07-02*
