Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
It's enormous. Yes, when you make an antenna bigger it captures more signal.
I think the point is that it functions better than other high-quality antennas of the same size. Read the source articles before criticizing.
I read the source articles before critizing. This isn't exactly the first article about this thing.
Yes, the double bay Gray-Hoverman outperforms a ChannelMaster 4228 significantly, by roughly 3dB. Being twice the size, it would of course pick up twice the signal. 3dB, by the way, is double the signal.
If you can get the parts cheap enough to save some money or if you really need an antenna larger than ChannelMaster can supply you, then build this thing. Otherwise, you can get a ChannelMaster 4228 or 4221 (depending on what you need) with a lot less hassle and it'll serve you well.
I use a ChannelMaster 4228 to receive HD signals from 45 miles away, despite mountains (multipath) and my refusal to put it on a tower on my roof ike I should, instead putting it in my attic.
I putting in a splitter (which attenuates 3dB plus) showed me I could even do this with a 4221. Too bad I didn't know up front, a 4221 is cheaper, easier to get into the attic, and easier to reorient in the confined space of my attic.
The single-bay Gray-Hoverman is 32"x40" and performas similarly to the 36"x40" ChannelMaster 4228. But they don't do this comparison in the article. They compare the 20"x40" CM4221 to the 32"x40" single-bay Gray-Hoverman. And they compare the 36"x40" CM4228 (which is basically a double-bay 4221) to the 75"x40" Gray-Hoverman. The Gray-Hoverman picks up twice the signal in both cases, by virtue of being twice the size.
And please remember that if you will use this antenna outdoors, consider wind-load. The bigger the antenna, the more wind-load. plus home made antennas are usually less sturdy than commercial ones. (Atleast mine are) But if you have the room to shove this in an attic then, this is great. more power to you.
