Summary: Best antenna I've ever had
Ever since the switch to digital TV, we've had nothing but problems with our existing antenna - channels breaking up or not coming in at all. We live between many stations - 60 miles to the south, 30 miles to the east and a major metro area 80 miles to the north. The existing antenna served us well when channels were analog, but it was time for the recycling bin. I read the reviews for many other antennas, and was apprehensive about this one for two reasons: 1- It's 15 feet long, how can I get it on the roof?, and 2- Other reviewers think it's fragile, will it last the first wind storm we have? After owning this antenna for about 2 months, I can finally answer both of these concerns. First of all, the box was delivered intact, and not banged around a lot, like sometimes happens. I assembled it fairly quickly on the ground and was able to hoist it onto the roof. I mounted it on my old mast, had everything back together and was watching TV within 2 hours of starting. This isn't my first TV antenna, but I'm far from an expert and this was by far the biggest and most complex antenna I've ever worked with. It's couldn't have been easier, in my opinion. Second, last week the wind blew. We had sustained winds of 20+ for 3 days, 30+ mph for two days straight, 40+ mph for hours at a time and gusts to 60mph. The antenna survived. and looks as good as the day I put it up. In spite of how fragile it may appear, it's as strong as any other antenna. Okay, so what about the picture quality? It's excellent! Last night, we watched a TV program being broadcast from 60 miles to the south, and the antenna was pointed north. It did break up periodically, but was still better than the old antenna pointed south. Overall, we are now getting every single TV station within 80 miles, and most of them are crystal clear. I'm very happy with the antenna, and would buy another one just like it. It's great to have the full capabilities of HDTV finally available to us!

Summary: Really big but ineffective
I bought this antenna to use at my cottage. It is about 30 miles from the broadcast signal but is mostly just coming straight across a lake. I have this mounted on my roof about 10-15' above my roof on a tripod mount. There are a few trees nearby but nothing much to speak of. As I said, the signal is coming pretty much straight across a lake with not much else to block the signal. It gives me a few more channels than I had without any antenna but my other TV with plain old $20 rabbit ears is actually getting a better signal and more stations. The other problem is that certain channels say that they are blocked due to some channel protection. I don't have this problem with my other TV so I'm not sure what's going on. I bought this antenna after tons of research because it seemed to do the best job from the furthest distance to the signal source. That has NOT been my experience. If I could do it over, I would try a few cheaper options before I bought this massive antenna. Another downside is that this antenna is about 15' long and 6' wide. It's HUGE! It's not a problem at my cottage because I don't have close neighbors but it is a real eyesore if you're in a neighborhood.

Summary: Weak Struts
I liked the antenna and it seemed to give good gain with moderate directionality, but the first flock of birds that decided to settle on the nice struts broke the two rear (longest) pieces and they now hang down like a broken branch, and we can not get Channel 2 anymore.

Summary: Crossfire Excels!
Channelmaster Crossfire 3671 and 7777 Pre-Amp If your like us and live on the fringe of mainland society, or in any case WELL AWAY from your signal sources, you'll need a solid `deep fringe' antenna to dial them in. With the switch to digital, many fringe areas that received analog signal in good order, lost out. Before Digital, or BD, we got our favorite channels on a clarity scale anywhere from well to acceptable. And while AD gave us ONE channel only with our old antenna, with our Crossfire 3671 and CM7777 pre-amp feeding a Vizio VW26 we not only get 20 some odd channels including all our favorites (except the weak powered Channel 9), but we get them in high definition and for free! We do have to tweak the antenna from time to time and we do lose our signal on occasion. I have to attribute this to atmospheric vagaries. Frankly, we brought in several of the leading deep fringe antennas for comparison purposes and NOTHING beat the Crossfire. At our distance from signal, I don't expect to get reception on a par with sat or cable. Oddly, I can secure transmission more often than not by playing with the leads going into the tele. Must be electromagnetic fields. I thought these cables were shielded. Guess not. On our remote island off the coast of Washington State, Seattle is the location of most channels we're looking to get and it is roughly 70 miles distant. We have a good southern facing toward the signal emission point at 139 degrees, SSE. There are tall trees in the vicinity of the house but the antenna points through a single branch and just clear of the horizon. We have it mounted in a low tech wooden cradle on the roof of an outbuilding (roughly 20 feet up). If you've got problems bringing in reception due primarily to distance from source, you might just want to reach to the top shelf and pick up a Crossfire and save yourself some time and money working up to it eventually. Highly recommended!

Summary: Awesome And Huge
Did a lot of research on this one. I have four 10' poles for this from Radio Shack, it is cemented 2' into ground. And attached at the gable on my house 15' up. With this antenna I'm still going to have to reinforce, it is much larger and heavier than you think. It's about 3 foot tall, and the length and width of a full size Chevy Saburban. I've got this fed into a Grounding block, which runs into a 6' ground pole via a thick copper wire rated at 60,000 volts. Do not put this thing in the air without preparing for lightning. Then it runs to a preamp, then into my house. I use a PHD-205 receiver, with an Optoma HD66 projector. I live in a small town about 45 miles line of sight from any city. I receive 30 channels with this, when I can't even get 1 with bunny ears. Without the preamp I only get 20 channels. The preamp doesn't get you any more channels, it just ensures you don't lose any signal on the way to your TV from the pole. I suggest visiting [...] to figure out about how many channels you will get. I also suggest hooking up a tv right at the pole, so you can get it twisted to perfection right then and there. Lastly, I suggest you reinforce this thing, 3 times as much as you think, cause it's huge.
