I am trying to model a BOG (Beverage On or in the Ground). I have access to
NEC4 and I am using the 4NEC2 interface.
As soon as I drop the antenna below ground level, approx. 2 ft. without
errors, I lose all indication of directivity except for a few dB. I have
tried different lengths from
Mike,
The reason the beverage wire in the model is 2 ft. below the surface is to have
it away from the ground somewhat and have a nice segment length from the wire
to ground on each end. The model shows only about 2 dB difference in gain and
no pattern difference between the wire 1” below

Maybe I've just been lucky, but the long runs of plain vanilla Commscope

Here is a PDF that has the plots and the NEC Model.

The cheapest protection would be Polyethylene sprinkler pipe. Better would be
rigid pvc electrical conduit. Either will be much cheaper than liquid tight pvc
conduit.
The sprinkler pipe would probably fight you and try to be coily, so I suspect
the rigid pvc conduit would be a better option.
I have never heard of anyone burying a BOG. The radials could be buried an
inch or so, but a BOG should lay on the ground or slightly above. 2 ft. is
two feet too deep.
About 200' is a common length for a BOG on 160.

If you are a serious contest op you should not be reading this get back
in the chair and work some more stations.
I have been asked to operate 160m this evening by several Caribbean
stations. Since they are all multi¹s they may have time to read this.

Worked a few guys with the 80 dipole last night. CONDX did not seem
great. I will try again tonight. Not that CO is rare but points are points!

Can you upload your patterns as GIF or PNG files somewhere, so that we all

Rock ledges probably mean directional drilling would be prohibitively
expensive. Even in soft soil it costs A LOT more than trenching. Same
for a Ditch Witch over ledge even with carbide teeth, but you might get
a lot of it underground.I put in 6000' of 1 water line (mostly PVC)

Worked them with one call, only running 200

a threepeat be possible with PQ0T?
This has been another great DXPedition.

a array of receive verticals (DXE 8 circle). I live in New England on a

I have some RG-6 coax inside some 1/2 PVC rigid conduit laying on the
ground. It feeds my 160m inverted-L ~250' behind my house. But whenever a
heavy tractor or truck drives over it, it breaks the conduit in two and
damages the coax.
If you are speaking of Sealtite flexible conduit, that'll

MST is - 7 hours from UTC, not -6 hours MDT has caused a mental problem I

Anyway 0500 UTC is the correct time for 10 PM Mountain Standard Time.
