Post End fed 66ft G4YKB
I have an end fed (with rg213 coax) G4YKB long wire.
It goes from my gutter at about 20ft to the bottom of my garden (24ft away) at an height of about 8ft, then across the bottom of my garden (16ft wide) at an height of about 8ft, then diagonally back up to my gutter terminating about 6 ft away from it.
I can't pick anything up on it. :banghead:
The only grounding is through the coax back to my tuner.
There is no grounding on the tuner (LDG AT200 Pro) or my Radio (IC-7100) apart from the -ve lead that goes back to my PSU (which I presume is insulated.
What can I do to get some reception?

You should be able to get an OK receive with 66ft of wire put into the center hole of the PL socket on your tuner. Try putting the antenna directly into the radio. If your not receiving a reasonable signal then there is a fault with your antenna or coax. Good luck.

What band are you listening on?

Besides the advice above you could also try using one of the more local WebSDR's and find a strong signal or busy band and do a compare.

Google websdr look for hackgreen or twente uni.

any one who runs a station without an earth wants certifying, i don't think much of your training. at least run some wire on the ground connected to the atu earth.

The PSU is earthed (mains) and the extra earth wire from the box on the power lead is connected to the earth terminal on the back of the IC-7100.
I will run a separate earth from that terminal to a ground rod I have, but it is going to be a long earth wire as it needs to go about 50ft from my bedroom (an earth STRAP is out of the question).

The screw in the middle of the back of your 7100 is the grounding terminal.

Hope this helps?

What sort of earth?
I don't run an external RF earth, and my station works just fine!
Then again, I am using balanced antennas and feeders.
Obviously the way he is trying to run the wire, and I am not completely sure how from his description, would possibly benefit from some sort of ground or counterpoise to work against.
But his description of co-axial feeder to antenna termination is vague to say the least.

Has your shack ever been hit with lighting? If you get hit your whole concept of earthing would probably change.

I'm second on the list, as the way I run my installations has never called for stakes in the ground, or ten ton of chicken wire buried under the lawn!
Until the OP states exactly how his 213 is terminated at whatever this long wire installation actualy physicaly consists of, suggestions of extra earths tagged "here there and everywhere", are pointless!

My end fed no longer has a earth wire running down the mast to ground, I tried earthing to the tower no loss or improvement so I was happy to do that :D
Sometimes the rule book can be broken.

Noooooo look back at the posts about the perils of earths, a counterpoise for each band is a better and safer way to go

I think it is a 66ft length of wire attached to coax via a 9:1 unun with an earth tag that you should run a counterpoise off.

The counterpoise is usually described as being optional. ;)

G0UEX is right apart from it doesn't have an earth tag, although the bracket may be earthed.
