ok....we go thru this often enough. here is hughes latest REQUIREMENT for installations regarding grounding:
FROM the dish to the ground block: rg6 dual shield with 17g messenger wire. messenger wire MUST be attached to separate bolt on an UNUSED portion of the elevation slot on the back frame. period. not the lug on the transmitter, not the mount, but the elevation slot. NO "double nutting", cant add a 1/2" bolt to the elevation threaded rod, or elevation bolt. MUST be separate bolt.
the ground block MUST be in a weather proof location (indoors ONLY, not under a deck or eve) or in a weather proof enclosure. PERIOD.
from the ground block, a minimum 10g GREEN ground wire not to exceed 20 feet, to an approved bonding point. longer ground runs are acceptable with larger gauge wire per specs. approved bonding points are: structural steel (commercial buildings or trailers only, must use i-beam clamp), bonded cold water pipes within 5 feet of water pipe entering the building (must use pipe clamp, not straps), electrical box (in and outside with pan clamp), house ground wire (using split bolt), and house ground rods (using acorn bolts). NON UL-Approved bonds are NOT approved and WILL fail QA photo audits. ie, cannot use a self tapping screw with ground wire wrapped around it to structural steel. the self tapper is NOT a UL approved item.
from the ground block to the modem, rg-6 dual. the total rg6 dual limit is i think 182 feet-ish. longer runs will -by spec- require rg-6 quad, rg-11, heliax......whatever based on ifl run length.
hope this helps.
Not even close to HNS requirements. Total BS, you must work for QSX, or you are a P-10 installer!

BTW, why do you need a feed horn?

| Greg, how many times have you typed the word 'ground'?
If you had a penny for each occurrence, you could afford to travel around the country fixing these ground problems, yourself.
I see one thing has changed over the years, though.
Now, the people you help seem more prone to take your advice...unlike me, and other smarta$$es, who thought we knew better until our systems just ground down to snail speeds.
I am tempted to blame Hughes for not getting shaped up after all this time, but I realize the problem really comes from installers trying to cut their time and costs, at the expense of the unsuspecting customer.
Anyway, glad to see that you are still hacking away at it...and wondering who will take your place when you are no longer able to remember how to spell 'ground'.
