Here's the advice offered by goforit in this thread:

Antennas Direct 91XG vs Antennacraft MXU59


Seems like the Winegard HD 9032 would be a better comparison to the 91XG.
Because the MXU59 was simply too lengthy for my attic access, I took this advice to heart and now have the Winegard HD-9032 in my possession. Since the boom is in two parts (10 reflectors on each segment), this antenna will fit.

The elements look exactly like those on the UHF portion of my HD-7696 (which, frankly, was a disappointment and didn't meet my expectations).

The one surprise is that, atypical to other Winegards I have, this doesn't use a balun cartridge. Instead it ships with a traditional-looking balun, black in color labeled only with "MATCHING TRANSFORMER" and no other hints of origin. For what it's worth, it doesn't look exactly like the AP-1000.

One minor annoyance is that there's not a strain relief on the boom for the balun's 300-ohm twinlead. There are two sets of posts, on the top for a VHF lead and bottom of the boom for the balun's attachment.

I'll be giving this new antenna a workout in the next few days to see how it measures up against the AntennasDirect 91XG. Since I do have a number of baluns on hand, I'll select the best of the bunch to get the least loss. We're fortunate in the Dallas area to have both channel 14 and 51 and a good dispersion of everything in between per TV Fool:

Post some pictures and detailed measurements. :)

It looks like the HD-9032 could also benefit from a wider reflector. At 15" wide, its probably only about 1.5 times the width of the driven element, which is about the minimum recommended for a corner reflector.

I find it interesting that NEC input files aren't readily available already. Maybe my search methodology was flawed because I came up with zilch. And the only pictures I've found are just the stock ones.

It used to be called the PR-9032 (exact same antenna) so maybe it can be found under that model number. (?)
No luck even with fuzzing up the search using these keywords on Google:

(nec|model) (pr|hd) 9032

Another oddity as I inspect it is the element count.

The published specs show 35 active elements. There are 21 directors (with both booms joined), 1 driven element (tetrapole), and a total of 10 elements on the corner reflector. My math shows that adds up to 32.

Ken Nist posted an EZNEC model of PR-9032. Heres the 4nec2 conversion:

It used to be called the PR-9032 (exact same antenna)
But theres a HUGE discrepancy between Winegards HD-9032 quoted dBd gain numbers here http://www.winegarddirect.com/viewitem.asp?d=Winegard-HD9032-UHF-Prostar-1000-TV-Antenna-(HD9032)&p=HD-9032

and Ken Nists calculated PR-9032 dBd gain numbers here http://www.hdtvprimer.com/ANTENNAS/comparing.html

I dont know what to make of it.

(My calculations of the above NEC file agree with Ken Nists, so its the same figures as in his chart graph. )

Pictures and precise measurements will be posted here in the near future (thanks to tripelo). In the meantime, here's a comparison of the AntennasDirect 91XG and the Winegard HD-9032 using a Sencore SLM-1456.

Refer to the post a few messages back for the TV Fool report for my location to correlate the channels with the facilities. Both antennas were tested in an attic (without radiant barrier) with an otherwise unobstructed path to the Cedar Hill antenna farm. The same 1.83m length of Monoprice RG-6 QS was used to connect from each antenna directly to the Sencore instrument, with no preamp, splitter or any other device intervening.

Now another set of numbers to compare the two UHF yagis: 91XG vs. HD-9032.

These are made after a 15.24m run of Monoprice RG-6 QS through a Channel Master CM-7777 preamp. The readings are from the "hdhomerun_config" tool connected to a SiliconDust HD Homerun device. The raw output of that application was cleaned up of extraneous information (such as "lock", "8vsb" and "bps" values) using a simple Perl script. Both were made within 15 minutes of each other with the antenna mounted in the attic (see previous post).

Since most of the facilities are so strong (along with high HAAT antennas) in this market, I think focusing on the low power stations (15 kW and below) would be of greatest interest. The LPTVs in the Dallas-Ft. Worth area are 18, 20, 25, 27, 31, 34, 38, 44, 50 and 51.

"New" Winegard HD-9032 (seen below a 9022):
Yeah, they look to be the same from a distance, but the specs for the HD-9032 show a much lower gain figure for channel 69 compared to the PR-9032, leading me to believe they may have fiddled with it a bit.

Winegard has for the HD-9032 14.9 dBd posted for channel 14 and 16.3 dBd posted for channel 32. Thats really out of whack compared to the 91XG numbers.
Just to show the difference in tablular form, here's a comparison (using the Sencore power levels posted) between the 91XG and the HD-9032.

The gain difference favors the 91XG in most cases. Only channels 27 and 40 show the HD-9032 exceeding the 91XG. Channels 20 and 50 have the same power measurements on both antennas. Across all 26 channels measured, the 91XG bests the HD-9032 by an average of 0.91 dBmV.

Nice work. Looks like the 91XG is still the top dog; curious to see how peano does with the MXU-59.

At 15" wide, its probably only about 1.5 times the width of the driven element, which is about the minimum recommended for a corner reflector.
Actually, looking at the model, the ratio is worse than that. The reflector elements are 14.6 inches and the overall width of the driven element is 12.2 inches for a ratio of 1.20.

re nelson, it would be nice if you could put some 2" X 4" mesh on that corner reflector, about 24" wide and retest. I wouldnt be suprised if you got better numbers than the 91XG :)

Unlike most participants here, I am a horrible DIYer. Ham-fisted, awkward, all thumbs and such. So, to pull this off, please be very explicit as a howto guide.

Do stores like Lowes or Home Depot carry 2x4 mesh? What material is made of? Do stores offer a service to cut it to size? How do I secure it to the corner reflector? What dimensions should the mesh be?

Talk to me like I'm a 4-year old. :) If that fails, knock another year off!

EDIT: Or could the existing corner reflectors from the 91XG be used? Can I somehow strap those onto the HD-9032?

Do stores like Lowes or Home Depot carry 2x4 mesh?
Yes, but I think the smallest roll of 24" high 2" X 4" mesh is 25 ft long. Lowes also has 1" X 1" mesh in a 15 ft X 24" roll for about $16. This will help the gain on the higher channels compared to the 2" X 4" mesh and in an attic you dont have to worry about wind resistance.
What material is made of?
Galvanized or green plastic covered steel. Ive seen black plastic covered steel, but not at Lowes or Home Depot. Typical gauges are 14 and 16 gauge. Either gauge is fine for a reflector.
Do stores offer a service to cut it to size?
A Mom and Pop type hardware store will, if you can still find one of those. Of course the price per sq ft is higher.
How do I secure it to the corner reflector?
In the attic, white or black nylon wire ties will do nicely and no tools are needed to use those. :p
What dimensions should the mesh be?
Using 24" high mesh, and knowing how the mesh runs, youll need a 48" length and just bend it in half on a 90 degree angle. The 2" side of the mesh will be running up and down vertically. Right at 90 degree bend in the middle, youll need to cut out a piece of wire right in the middle to accomodate the boom. Then just wire tie the mesh reflector on to the back of the existing corner reflector.


EDIT: Or could the existing corner reflectors from the 91XG be used? Can I somehow strap those onto the HD-9032?
Man, thats a lot more involved work than the above.

Actually, now that I remember your installation is in an attic, a cheaper easier alternative is to get 2 pieces of thick stiff cardboard, 2' by 2', cover them with aluminum foil, and just duct tape them to the existing corner reflectors. :)

Another option from the $1 store is to get cooling racks in the aluminum pans etc section of the store. They are 2/$1. The cooling racks will also give you additional gain on the high channels over the 2"X4" mesh. Youll need 6 pairs (actually, just start off with 4 pairs and then see if another pair will fit on top on of the rest) and still the wire ties. Just strap the cooling racks onto the existing reflectors, neatly side by side (the cooling rack bumps facing backwards towards the TV transmitter, but really it doesnt make much difference). Lay the cooling racks so the 3/4" wire spacing is vertical. Cheapest place for UV resistant black wire ties is Walmart Automotive dept.
With this method, absolutely no tools are needed, good enough for outdoor use, and the cost is less than $10, heh. The finished width when your done should be about 27 inches, IIRC the dimensions of the cooling racks.

I hope Ive made these directions clear enough, but please ask if anything is unclear.

I'll take door #3. Duct tape and cardbord are definitely the materials of choice for a guy like me. Now I just have to remember how to work a pair of scissors! :)

I'll try this on Thursday night and report the results. But to be clear, should the aluminum foil cover both the back and front of the 2x2 cardboard or just the front?

Thanks much for a simple hack.
