[TowerTalk] Terminate braid at top of tower...or not?

[Jim Thomson]

Is it better to ground the braid of the coax coming from a yagi.... to the top of the tower, or not?     I will be using a remote switch box at top of the crank up tower, as
I don’t want to use more than one coax going up the side of the motorized tower.....to save weight.  I could use the metal box....and ground all the braids of the coaxs
form the yagis to top of tower.   I can also use a waterproof plastic nema box....and float all the braids from the top of tower.   IF I use a plastic nema box for the remote
switch box, I can install a single choke balun on the input of the remote switch box..... to  supplement the individual choke balun at the feedpoint of each yagi.  The thought
here was, if a metal box is used..and residual RF that gets past the yagi balun...will then flow down the tower legs..rendering any balun at input to remote switch box useless.

Another plan was  to install a rf choke balun on the output of each port on the remote switch box, is a metal box was used. Again these baluns would supplement the yagi baluns.

At the base of the crank up tower, the hofi lightning arrestor will be installed, aprx 4 feet up one tower leg..and bonded to tower.   It will also serve as an interface between the
larger LMR-1200DB  rigid coax  from shack to lightning protection box...and the smaller RG-393  running up the side of the crankup tower.   IE:  braids of both coaxs will be bonded to
base of tower.   Each tower leg gets a 2 ga stranded, bare  cu wire  going to its own individual 8 ft ground rod...and cadwelded  at ground rod.    Top of each rod is aprx 5 inchs below
ground level,  buried below the lawn, on the perimeter of the concrete base. 

Shack end of LMR-1200  has its braid bonded to a SPG on basement wall.   I also ran 2 ga cu wire from base of tower to a 4th ground rod outside basement.  Then more 2 ga cu from
4th rod to SPG plate..aprx 4 ft.  4th rod is cadwelded too. 

Main issue is whether to bond coax braids to top of tower..or not.    Or does it make any difference since braid of 393 going up the tower is bonded to base of tower anyway. 
All the braids of all the yagis  will be bonded to the braid of the 3093  running down the tower. 

Any comments on the proposed plan ?
