Sorry about the typo...it's RCA ANT-751, not 741.
BTW: You can have it shipped to your local Walmart for no extra charge
and return it to the store for refund if you are not satisfied:http://www.walmart.com/cp/Returns-Policy/538459
It's becoming more and more difficult to find antenna specs from the manu's.
Here is C-M's 2008 Catalog, with specs for all antennas summarized on pg6:http://www.starkelectronic.com/cm2008.pdf
More info found at http://www.hdtvprimer.com/ANTENNAS/comparing.html
Note smallest Advantage (CM-3016) is 83.6-in WIDE...others 95-in.
That makes it even more difficult to ALIGN in-between the braces in a typical attic.
Also note that C-M does NOT provide Gain specs for their new CM-5xxx series.
Since they're new, they cost a lot more....and I didn't see any on Fry's website.
Also note that Fry's in-house selection at OUR stores is very limited and seems
to change from visit to visit....but they always seem to have obsolete Advantages....
I thought we were discussing an upgrade from your indoor antenna,
rather than the biggest, MONSTER antenna that belongs outdoors on a mast.
Spec sheet for W-G HD7084P et. al. can be found here. It's 110-in WIDE, 131-in BOOM
and 25.5-in TALL, with less UHF Gain than compact CM4228 and about same Hi-VHF:http://www.winegard.com/offair/hdtv-...r-antennas.php
CM4228HD cost is lower...even if you add YA-1713 or Y10-7-13 Hi-VHF Hi-Gain antenna.
Although it's difficult to find unequivocal "proof", I believe the distributed bow-ties
also have an advantage in the multipath frequently encountered in attics....some of
them might be in a NULL, and others probably NOT....
BTW: I should also mention an easy to construct DIY project, the M4 Super-4-Bay Bowtie:http://m4antenna.eastmasonvilleweather.com/index.html
[Note partial "kits".]http://imageevent.com/holl_ands/multibay/4bayrefl/m4swp
The whisker length is optimized for the new UHF Band, rather than the older 4-Bay
and 8-Bay antennas (e.g. CM4221HD and CM4228HD) which were optimized for the
OLD UHF Band, resulting in loss of Gain in the lower UHF Band. The Reflector in the
M4 is 36-in wide x 40-in tall, which optimizes performance in the Hi-VHF Band much
better then the narrower Reflectors in the CM4221HD and CM4228HD. If you compare
Gain curves you will be surprised to see that the M4 Super-4-Bay Bowtie greatly
exceeds the performance of ANY commercial 8-Bay antenna for both UHF & Hi-VHF.
AND it's far more compact than ANY of the other Combo Hi-VHF/UHF Antennas....
It could even be put on a rotator in the attic if that is desired....
