GRA-750B 7-56MHz Wideband Broadband HF Vertical Mobile Antenna, 120W(SSB), 40W(FM), 48.03 inch, PL259

Q: How well does this perform while actually mobile? Does it hold up to driving speeds?

This is heavily built antenna and it should hold up to driving speeds. Your limit will be the mount you use because it is very heavy compared to a hamstick or hustler. It is on par with a screwdriver antenna when compared. Having said that I returned the antenna because the RX signals were weaker (a couple of S-units) than the Hustler or Diamond low band antennas I already owned.

Q: Let me clarify my question - i don't mean, "should i short the center pin" i'm asking if it's shorted as manufactured. mine is shorted. is that right?

It is shorted to DC not RF, so there is either a transformer or tapped inductor in the lower housing. If you have an antenna analyzer you will see this when connected it to the antenna when installed.

Q: How do you mount this for mobile operation?

I used a 5” mag mount. Antenna has stayed on the truck at up to 80 mph.
