[TowerTalk] M2 OR2800 Terminal Box Question

[Mark Robinson]

I am putting together the diecast terminal box for my M2 OR2800 rotator. 
This is a sealed diecast box that mounts on the tower just under the 
rotator. It connects to the rotator by a short cable and the rotator cable 
to the shack also enters this box.   I have a couple of questions.


1)    This is a sealed box but I am thinking that it might be a good idea to 
drill a small weep hole at the bottom of the box. 1/8 hole maybe. Is this is 
a good idea.


2)   This rotator uses a pulse positioning sensor and this pulse signal is 
fed via a shielded cable as part of the rotator cable assembly. I have 
grounded this shield at the bottom of the tower and at the SPG. I think that 
I should ground the shield at the top of the tower inside this box as well. 
I have added a small grounding pigtail attached to a screw inside the 
diecast box. Is grounding the shield here a good idea?
