Need spec sheet for Mark STL antenna

A

artsutton

If anyone has an internet link to a spec sheet for the 4 ft Mark STL dish antenna, would appreciate the info. I need to provide it to a tower owner. Checked out General Dynamics website and some others but can't find the actual spec sheet that gives weight, size, etc.

Thanks. My direct email is [email protected]
 
Already sent the info to Art, but Tesco has these things, their stock no. 61620

It's a P-9A48GN-U, weight 105 pounds, 4' dish, 19.20 dbi gain, 17.5 degrees beam width.
Rated wind load 125 mph.
 
While we're at it, does anyone have specs for a 10 foot Mark STL dish? I've got one sitting around out back, because we can't find the specs, and I don't want to use it without knowing them. For private messages: [email protected]
 
Not on these models--remember they are round, dish type antennas. With something like a miniflector, you only have a partial grid behind the driven elements, so I would imagine the tower might have some effect on beam-width when you rotate it either vertically or horizontally.
 
Ahh. It's the Gabriel 8' RFF4-940ASE dish the stations I work with has a sligtly wider beamwidth horizontally. Used that brand on the 7200' mountain top since it has a radome.
 
Thanks, Tom! I'm inclined to trust the 27 dBi gain figure more than 24.6 dBi, since 27 dBi is closer to what I'd expect for this antenna size, and because Hutton quotes the same 24.6 dBi figure for the 8 foot version of this dish (http://www.hol4g.com/ac/product.aspx?number=TPG-P-9A96GE-S&p=248137&sc=3562). I think there was a typo… Also the dish can't be 610 pounds, considering that it's made of aluminum tubing, and I can move the dish around by myself (on the ground). Either that's the shipping weight (with a lot of packing material), it's a windload figure, or Hutton just plain messed up.

My old RFS dos program lists this model with 27 dbi gain and a beam width of 6.6 degrees.

Hutton Communications lists it with 24.6 dbi gain and weighing 610 pounds:
