new coax cable runs

been in the garden this weekend twiddling with my twigs. i have four points and each one has its own cable and all run to the shack (upstairs back bed room)

Anyway as you do I have been installing each one with what i think is the best coax for the job and the best i could afford. I am happy with it all, swr is low and noise is good too.
Where I wonder is like a lot of others is with the RF Gnd.

what i have at the moment is a seperate ground running 16mm2 earth cable to a fixed earth ground bar with bulkhead connectors running through it. All the feeds terminate into it and small leads run to the radios or i can go direct to the radio if i wish.

heres some pictures



heres a rough lay out of the cable runs in the garden



and doodles


the land lay out


present cable runs in use HF and U/VHF

and my present set up


that just leaves the questions how good is it and can it get improved or made safer?

for lightning i just disconnect every thing
for RF gnd its okay i think but what do i know?
maybe i should have the lot grounded at scource and then run to the shack.


what do you think of it?

2/70/6 set up with a dirty air balun coil



G5RV feed point on the right, cables loose due to house painting



should i do a air coil balun at the bottom of the 10m/11m, no other reason , than, i have spare cable to do so

You need a RF choke on the 10/11m antenna much more than the 6/2/70 one.

4.25"/110mm former (ground waste pipe is perfect) and 5 turns of coax around it.
