We use ptp650 and ptp670.
450i
PMP450 did not have a metal grommet it was plastic so the ground kit was
the only way to get energy pulled off cable.
The ground screw was the only thing to ground the radio.
I have not looked back since using the CAT6 bbdge cable with the ground kits

So do you use the PTP600/650 LPU, or do you use the grommet right in
the bottom of the 450 radio? Original 450, or 450i?
How do you ground it at the base of the tower?

BBDGE is the best way to go and to answer your question about ground
kits is yes absolutely..
As far as termination that way its done today is to prep cable so
that about a .5" of armor is exposed and rj45
sits about .25" from armor. This is because if using a steel grommet
that the grounding cleets will snug down on the
armor that was exposed near the head.
if u can find a user manual for cambiums LPUs it has an excellent
picture of one.
This has been our standard since the first pmp450 arrived.

Does anyone sell custom length, per-terminated BBDGE cable? I have
an application where I need the copper cladding tied to the shielded
RJ45.
Also, has anyone used grounding kits on the cable for mid-span
grounding? Will Coax cable kits work on it?
It's been years since I've worked with that cable, I think back when
it had to be punched into the PTP400 LPU Units. I remember it being
a pain to field terminate.
One of our tower sites just put up antennas at 6.9, 9.2 and 14.7mhz
and it's causing all kinds of Ethernet problems for our cables that
pass through their array. They want to run at 5-6kw, and we start
having problems when they go over 2kw. They are hoping that if we
change to the BBDGE cable with lots of Grounding, it will fix the
problems. Already have Coils at the top and bottom on Beldon7919
cable. That got us from 400w failure to 2kw failure.
