satellite antenna photos oa4o
Hi all! http://www.flickr.com/photos/n3ykf/ oa4o is the Peruvian national club station. There is a fine az el antenna array for vhf, uhf and shf.
They don't know what manufacturer or model the antennas are. Do you? Top 4 photos.
Next time I go down the possibility of rehabbing the array exists. The club president expressed a serious interest in the satellite gear being used. 73 de Norm n3ykf
2M looks like a KLM 22c with polarity switcher 70 cm looks like a KLM 40cx with polarity switcher 1.2 G looks like a Tonna (F9FT?) http://www.f9ft.com/indexe.html

I agree with Mike, N1JEZ. The KLM's were the only one with the big box polarity switcher on the end of the 440 boom. The 144 unit was not covered but an open circuit board with lots of exposed phasing wires.
In fact looks exactly like mine except mine have the F9FT in the middle of the boom. If you need copies of the KLM manuals let me know .....
I have a set of older Cushcraft antennas that meet that criteria: 738XB and 22XB. Both have polarity switching but the 435 ant has the box on the rear. I have manuals for both.

Hi John,
The 70 cm antenna could be Cushcraft, but I think the 2M is KLM because of the configuration of driven elements. Folded dipole vs T match.

Bill, John and Mike, I would love copies of the manuals. Please forward them on as I will pass them along. What era are these antennas? The 70cm one tests good. The rest need work. Has anyone done anything to rehab these? Norm

Agreed, I have the KLM 40cx as well and that is definitely what that one is.

That's exactly what the 2m and 70cm antennas are. Here is the same Antenna setup in my backyard :-)

I have copies of the manuals if needed, I can copy them and mail mail. Just let me know...
