### Im assuming that the top of the tower..or a qtr wave back from the
feedpoint of a yagi, say on the boom itself on a 10 or 6m yagi, would be a low Z point ?
I may well be wrong, depending the height of the tower, and how well
bonded it is to the ground....say via 3 x 8 foot copper clad grnd rods,
and cadwelded 2 ga cu wire to each tower leg.
## any harm in bonding the braid of the coax to the boom, on the
xcvr side of any feedpoint balun ??
I'm not sure why you would say that. Are you assuming that particular
bonding point has a low impedance to ground? If so, I wonder why?
