Christpuncher, you didn't mention which of those antennas (there are quite a few different ones) so we need you to post about which antenna you meant into our Antenna Research & Development forum so that our OTA Antenna gurus can do a proper technical evaluation and analysis of the design.

Until then we'll continue to laugh at those stupid garbage antennas and feel sorry for the folks who mistakenly buy them. For a similar amount of money (or less) everyone can get the antenna(s) that will work best for them.

There is a big difference between working and being good. With a good signal, almost anything will work and with DTV, you won't notice a difference since the picture is perfect up until just before you loose the signal completely (there is a small window where you get pixalation and drop outs).

Here at DHC we like to recommend good antennas that will continue to work when the cheap ones stop working. It is the old adage, you get what you pay for. After all Murphey's Law says that your reception will cut out when you least want it to (the dead of winter when you don't want to get on your roof and during the most important program to you). ;)

I did a roof install today for a nice older gentleman who had bought a combo UHF/VHF antenna of a dubious brand name. The antenna had an integrated amplifier and rotator.

Of course I discussed the cons of buying such equipment, but the antenna was affordable for this cash-strapped pensioner.

Surprisingly, the antenna turned out to work reasonably well. The one concern I had though is that it used non-standard cable and connectors on the 50' or so of cable that was provided between the antenna and control box (rotator control, signal, and pre-amp powering). This of course makes grounding and lengthening the cable run difficult. (the cable is smaller than RG59--probably what's known as "mini" coax).

Further, the rotator control had no direction indicator. You can rotate, but have no idea where the antenna is pointed.

The caveat here: If you're considering a "junk" brand (and I don't recommend it), avoid any models that use hard wired non-standard cable and/or connectors!

Jase, my neighbor installed one of those same Chinese made 'junk' antennas up on his roof using the same tripod that his LOOK TV antenna was once using... it didn't last the winter... by spring it had fallen apart. I watched it self destruct over the winter from my kitchen window. :rolleyes:


Looked like this when new

That's a great point that needs to be made: if a person thinks a junk antenna is a great deal, wait until all the $$$ are added up after replacing it! :eek:

The moral of the story is to buy good OTA gear the first time. :)

HDTV101, yes no doubt I'll be hearing from this fellow over the winter or come spring to discuss replacement. The rotator housing is plastic; I've never seen that before! And the type of plastic that quickly becomes brittle after some UV exposure.

I told the gentleman to never attempt rotating with snow or ice on this antenna. It would likely kill the mechanism immediately.

Was at XS Cargo picking up a few Seiki BluRays on Boxing Day when I chanced upon a Belkin "Pure AV HDTV" antenna. $10 refurb so no returns. Took a chance as I can't find any Philips/Zenith Silver Sensors to hook up to the HDTV I bought for the basement rental.

This antenna though boosted can only receive the 2 CBC channels and none of the other 5. Tested the TV using my existing Philips and it gets all 7 channels with excellent levels (only difference is that the Belkin sits one level lower and has to go through a wooden wall - Philips direct LoS is obstructed by similar wall but big window is just under LoS.

Pure junk so stay away.

This one is Jensen's Passive TV Antenna, the model 611.

Passive, they call it. There it sits very quietly, looking out the window, oblivious, lethargic, solemn, apathetic, pensive, dispassionate, bland, meek. Some people think it's really "deep", maybe heavily sedated, or perhaps a bit absent-minded. Others mistake the staid, placid vibe for serenity, pondering whether this Asian product is Confucian, maybe Zen Buddhist. No matter, it is guaranteed to retain its passive composure while you rant and scream at it about the awful reception.
Trying to recover... I've been laughing for 5 minutes straight!

Look TV Antennas

Not sure if this has been mentioned, but I've been seeing plenty of former LOOK TV antennas for sale (used, obviously) as "TV" antennas. Buyer beware, of course. Look TV--before they ceased operations--used high-frequency spectrum that's much higher than (and thus incompatible with) broadcast spectrum.
