Another 2M antenna question

I was offered (for free) a VHF TV yagi anntena w/ rotor. Question: would
this work a 2M antenna? With a tuner, maybe?

Yes, it will work. I just tried it with my HT. From southeast of San
Diego, I raised a repeater on Mt. Santiago, Orange County, with a 75-ohm
directional VHF TV antenna and a half-watt signal. Santiago is 70 miles
away. Disclaimer: My location, on a small hill with a generally clear view
toward the North, gives me an advantage.
Then, I put the analyzer on that antenna and I was surprised to find the 2m
VSWR was 3.1:1, worst case. Losses through about 50' of cable from here to
the antenna no doubt helped my VSWR number.
There is some risk of using it with a high-power rig if the rig isn't
internally protected against operating into an excessive VSWR. Most are.
Start at a modest power and see what happens. That's what a lot of hamming
involves ... try it and see. Smoke is possible but not common.
