Default 150 Mile Antenna Claim

For those of us that live in fringe areas a claim that an antenna could receive statons from as far away as 150 miles is very tempting
But in real life the curve of the earth would make this impossible
(right) ?.

Not on your life. Bogus claims, poor antennas. If it sounds too good to be true it is. Had a friend buy one of these cheap things, what a piece of junk. Didn't perform as any of it claims stated, was cheaply made and had trouble bringing in signal when compared to the current 4 bay UHF antenna he already had in place.


Let the buyer beware

Deep fringe reception requires specific equipment and a lot of factors to align. Even then, the signal to noise is way too questionable, especially considering the digital cliff, to be considered a reliable solution to the distance factor.

I've read a few posts about these antennas being junk. I'm very surprised they can make those claims without being sued. They must figure that people are swayed by the futuristic styling and colorful ads.

If you look at the top of this banner ad - you will see those exaggerated antenna's for sale.

Yes it will work, as long as the antenna is 100 miles long.

The loss in the antenna though would be so great and the gain so small - you wouldn't be able to turn it.

VHF reception 1 - 100 miles, UHF reception - 65 miles reliably.
Anything more then that is a exaggeration.

That in itself is an extreme exaggeration...

Remember when CB radio people use to talk on Skip. About 1980 I built a beam antenna in an attempt to receive channel 7 in Evansville Indiana from my house in Murfreesboro TN. I hooked it up but it did not receive channel 7. I just left the antenna up there on the tower after spending so much time on this project I didn't want to waste any more time taking the antenna down. Then I remembered my friend Bob Effland telling me how skip works better some days than others and it works better certain times of the day. So every time I watched TV I would try channel 7 just to see if anything would come in but it never did not for a long time. Then one day I received channel 7 Evansville for almost 30 minutes then it was gone. Then I got to reading about skip in my Amature Radio book, it said skips works best over a long distance like 1000 miles or more. The book also says when the sun is low on the horizon it come help improve signal by light wave probagation. I aimed my channel 7 beam antenna toward the west coast of California and left it there for months. One day while flipping channels I received channel 7 in California 2000 miles away it was Channel 7 News and Weather. Channel 7 from California was a little hard to watch at first but the signal got stronger over a period of 5 minutes until it was crystal clear for about 5 minutes then the signal started to fade and another 5 minutes it was gone. I tried many times for over a year but never received it again. It is possible for an antenna to receive some unbelieveable stuff but it is nothing you can depend on being there every day when you want to watch it.

I basically agree that the only way such a over hyped antenna could get reception 150 miles away is through skip.

After all, in 150 miles the earth curves almost 15,000 feet. Meaning there are very few places on earth where the Antenna could get LOS reception. And even then, given the fact that television signals lose strength with the inverse square of distance, just about means reception will not only take skip, but will also require the high clouds focus the signal like a lens.

Sure it can happen, but it happens very rarely.

These little craps of an antenna are just a bit of bent wire that looks like an antenna with a pre-amp attached.

Not worth much more than the box they come in.
