Physical Survey - Tripod question...

I am dispatched to run a test link from various locations on the ground and on roofs. I end carrying a lot of gear around to make this happen in an efficient manner.

I am trying to lighten my load.

Right now I lug around a 7’ non-telescopic tripod to mount my dish/radio on. I would love to find a much lighter tripod.

Does anyone know of a tripod that meets the following:

Aluminum
Telescopic Legs
Center extendable mast
Can withstand an arm ubolted to mast, 2’ dish and radio hanging on it.
Lightweight and folds to around 5’ or less?

I cant seem to find one. Basically I want the same thing I have now only smaller.
