What a score that was. 

There’s lots of pics of them in use on M151s in Southeast Asia if you look.  They were also the AMU used on the AN/MRC-108 FAC pallets.  They were a little more versatile mounting-wise than the MX-6707s because the spring base itself could be unbolted and re-oriented so you could mount the tuner base horizontally or vertically, both of which you see on VN-era M151s.   Countries like Canada would mount them as one tuning base in a two-set installation and use an MX-6707 for the other on pre-ROPS M151s and M38A1s.  

Interesting to see them made as late as 1986.  Who was the manufacturer?  I don’t think I’ve seen any later than 1968 contracts and I think they were all made by Magnavox.  Really high-quality bits of kit, those.

All-

I was able to purchase two NOS in box MX-2799s with whips and all mounting accessories recently for $50 at the Phoenix MV show.  Most people don’t know what they are and pass them by!

I had thought they were used exclusively on armored vehicles, but I guess they pre-date the AS-1729.  Anyway, the units I purchased were manufactured in 1986.  Looks like it belongs on my  M-715.  Probably a bit much for a poor little MUTT!
