Does anyone know the combined sq ft wind load of the 91XG + YA-1713 on a 5 or 6 ft rotor mast?

Quote:
Per Antennas Direct Install Instructions (pdf top of page 2) :

"When using separate antennas, mounted on the same mast, try and keep at least 4-6 feet vertical separation between antennas."

Neither Antennas Direct/Terrestrial Digital or Winegard publish wind load specs for any of their antennas. Thanks

I've read the windload of the 91XG / YA-1713 combination may be in the range of 4-6 sq ft.


Does this estimate sound correct?

Precise information is hard to come by. The only major manufacturer that routinely provides this information seems to be Blonder Tongue. The only thing Winegard has published recently is that the windload (actually maximum cross-sectional area) for the HD8200U (their largest VHF/UHF antenna) as 5.5 sq. ft. You can get an idea of the YA-1713 by comparing it to the specs of the Blonder Tongue equivalent. Unfortunaley, Blonder Tongue's broadband UHF antenna is not of similar design or size to the 91XG, so you cannot use it as a benchmark. My guess is that the combined windload of the two antennas does not exceed the estimate you have.

The 91XG is about 1.5sq ft(~35 lb lateral force @80 mph).A 10 element highbander is around 1 sq ft.Doesn't take much mast to hold these up.


My UHF install is around 12 sq ft w/masting.Now we're talkin windload.


Winegard has specs for all the antennas they sell.They are quick to respond to such a request.

Thus, per Max HD: 91XG + YA-1713 = ~2.5 sq ft.


Thinking about the windload on the rotor, does this estimate include the required "4-6 feet vertical separation between antennas"?


Your 6 UHF yagi install looks industrial grade.

From how far away can you pull in dropout-free reception?


The wind load data is not listed on the Antennas Direct or Winegard spec sheets. When I requested this info, they both replied that wind load data is "not available".

Thanks!

FWIW I've had the YA-1713 since 2002. It has survived several hurricanes and tropical storms including Charley which produced 110 MPH winds at my location.

That sounds encouraging. Do you also have a UHF antenna on the same mast?

Yes, i have the Televes DAT-75 and the YA-1713 on a 6ft. mast using a CM 9521 rotor and a 40ft. Rohn tower. The Televes also survived with no issues.
