Combinatino UHF and VHF-high antennas? |
|
|
Right now, all of the ATSC transmitters in my area are UHF, but
I'd be surprised if the stations with VHF-high NTSC
trasnmitters don't switch ATSC to their VHF channels in '09.
Based on my 1 quarter of fields as an undergrad, I would think
that a good combo UHF/VHF-high antenna would be a lot more
compact than one that does VHF-low as well.
Are there such UHF/VHF-high combo antennas now?

The Channel Master 4228 is UHF only, but does high VHF just fine.
Channels 10 and 12 come in with no problems in southern CT.

There are plenty of combination U/V antennae on the market for this
application. Channel Master, Alliance, Etc make some very nice items. Google
Search for TV Antennas will give you a plethora of information,

Based on the published dimensions and specifications, all of
the VHF/UHF combo antennas I've seen appear to be designed as
3-band antennas (VHF-low, VHF-high, UHF). A VHF-high, UHF
combo that disregarded VHF-low wouldn't need to be nearly as
large as any of the V/U combos that I've seen.

You can buy the yagi-style antenna that covers all 3 bands and just
cut off the end of the boom with the largest elements. You'll have to
do some research first (maybe check out a VHF-Hi antenna for size), but
that should do what you want.
As others have said, though, the Channel Master 4228 does just fine with
VHF-Hi even though it is supposedly a "UHF-only" antenna.

Click on Antenna basics, then try common TV antenna types &

Thanks, but I'm not sure what question you're answering.
I asked if there were combo antennas for VHF-high and UHF.
Based on the published dimensions and specifications, all of
the VHF/UHF combo antennas I've seen appear to be designed as
3-band antennas (VHF-low, VHF-high, UHF). A VHF-high, UHF
combo that disregarded VHF-low wouldn't need to be nearly as
large as any of the V/U combos that I've seen.
If you know of a VHF-high/UHF combo antenna, I'd be interested
in hearing about it, but I don't really need a page on antenna
basics (though I have a BS and MS in Electrical Engineering,
but most of what I know about antennas was learned from the
ARRL handbook and various magazine articles back in my HAM
radio days).

Yes, I know. Or I could trim the VHF elements to the correct
size. Or I could design and build my own. Or I could use a
"UHF" antenna.
However, the question I asked was "is anybody selling
VHF-high/UHF combo antennas".
Based on the answers I've gotten pointing to antenna theory and
VHF-low/VHF-high/UHF combo antennas, I take it the answer to my
question is "no."

Have you even bothered to try to find out for yourself? There are less
than 5 reputable outdoor antenna manufacturers, so hitting their websites
would take just a few minutes, and you would be able to answer your own
question.

As I already said: Yes, I did look at a several of the antenna
manufacturer and retailer web sites and didn't find any. That's
why I asked here. If I had found them, I wouldn't have asked.

I haven't seen exactly what you want, but AntennaCraft has their model |
Y10-7-13, which covers VHF High only . This has some advantage over a
combined antenna in that you can aim the UHF in a different direction, and
pick the UHF gain independently. Sells for $32 at www.warrenelectronics.com
.. Not a small antenna, but still 1/3 the size of an equivalent 2 - 6 ant.

I do not believe that Antenna MFGRS have yet to 'name/advertise' a
VHF-Hi/UHF antenna yet.. The Final digi frequencies should be
Chan 7 thru Chan 51.... Antenna Manufacturers have to lop
off VHF-Lo and UHF Chans 52 thru 69... Since these Chan
2 thru Chan 61 are in use today... This may not happen for
2 or 3 more years.... and Digital Chans 2 thru 6 may still
exist in Alaska & other remote areas for some time....
There are a few web sites on antenna performance thru GOOGLE...
That tell you by graph that a Channel Master 4228 UHF does cover
Chan 7 thru 61 very well... This is what you want....
however it is not advertised that way |

I don't want one. I was just making two observaions and asking
one question:
1) It appears that in many markets VHF-low (and the high end
of UHF) will not be used in the future.
2) A combo antenna for VHF-high/UHF would only need to be
about 1/3 the size of standard combo antennas that are
also intended to cover VHF-low.
3) Has anybody started selling VHF-high/UHF combo antennas?
After getting quite a few pointers to large combo antennas that
cover the VHF-low band and to UHF antennas that don't suck in
the VHF-high band, it looks like the answer to my question is
"no".
