## Product: Channel Master EXTREMEtenna Long Range Multi-Directional Outdoor TV Antenna - 80 Mile Range - Preassembled - Install on Rooftop or Attic | CM-4228HD 100 Mile
**Brand:** Channel Master

The Channel Master EXTREMEtenna CM-4228HD is built to grab both VHF and UHF signals, so it’s pretty versatile for picking up a range of local stations. From what we've gathered, it's a dual-band antenna, which should cover most of your typical broadcast needs.

The manufacturer mentions it covers VHF channels 7-13 and UHF channels 14-69, so it’s designed to work well with both. Our research suggests it's pretty solid at capturing multiple channels efficiently, especially UHF.

That said, while it can deal with VHF signals, it really stands out with UHF. Some folks have mentioned you might have to fiddle with the positioning or possibly add a [preamp](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dpreamp%26tag%3Dssw.ans.tx-1-20) to improve VHF reception. This especially applies if you're in an area where VHF is more common or those signals are weak. 

But with a bit of tweaking, most people found it does a great job across both bands. 

Now, about using it in an attic: Although it's mainly marketed as an outdoor antenna, many have had good results using it indoors or in the attic. According to our research, it can still pull in a decent signal from up there, provided that the structure and materials of your house don't heavily block signals.

Positioning is really important—getting it high up and aiming right at the broadcast towers can make a big difference. If you set it up in the attic, you might want to experiment with different spots to get the best reception. 

And adding a [preamp](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dpreamp%26tag%3Dssw.ans.tx-1-20) could be helpful if you run into signal problems. 

All in all, this antenna seems like a solid option, especially if you're more focused on snagging UHF channels but still want decent VHF coverage too.
