David,

The BURY-FLEX (TM) that is offered by the Davis RF Co.
is also pretty good stuff too. ~ RHF

-But- It Too Is Over Kill For Shortwave Radio Listening (SWL)
"Receive Only" Antennas.

? WHY Use RG6 Quad-Shield Coax Cable over RG8 and RG58 Coax
Cables for Shortwave Radio Listening (SWL) Antenna feed-in-lines ?

Practically Speaking Coax Cable Attenuation and Cost :
http://en.wikipedia.org/wiki/Attenuation
For a "Receive Only" Shortwave Radio Listener's (SWL)
Coax Cable feed-in-line RG6 Coax Cable still has a lower
dB Loss per 100 Feet then RG8 and about 1/3rd the Loss
of RG58 Coax Cable measured at 10 MHz.
http://www.davisrf.com/coax.php#attenuation
Plus most of the time RG6 Quad-Shield Coax Cable will
Cost-U-Less then RG8 & RG58 Single-Shield Coax Cable.

The Key Characteristic that both RG8 and RG58 Coax Cables
have over RG6 Coax Cable is that the Outer-Shield is "Copper
Braid" which makes them both better at handling RF Power
for Transmitting then the RG6 Coax Cable.

The Key Characteristic that Quad-Shield RG6 Coax Cable has
over both RG8 and RG58 Coax Cable is the Four Outer Shields
for better protection against extraneous RF Signal Penetration :
Since RG6 is by-design a Coax Cable that is most often used
in "Receiving Only" applications such as 'Free' Over-the-Air TV,
Cable TV, and Satellite TV; for Weak Signals and Signal Protection.

IMHO - Quad-Shield RG6 Coax Cable is a natural choice for
many Shortwave Radio Listeners (SWLs) looking to Reduce
and Eliminate the Ingress of RFI and EMF into and along their
Shortwave Antenna's Coax Cable feed-in-line.

COST - Often Quad-Shield RG6 Coax Cable has a Lower Cost
per Foot then both RG8 and RG58 Coax Cables.
EXAMPLE - 100 Feet of Quad-Shield RG6 Coax Cable at WalMart
http://www.walmart.com/catalog/produ...uct_id=7811235
for $33 which is 33 Cents per Foot -vice- 69 Cents per Foot for
RG8 Coax Cable at a Amateur {Ham} Radio Specialty Store.

AVAILABLITY - Also Quad-Shield RG6 Coax Cable is just
about Available Anywhere from : Home Depot, to WalMart,
to Ace Hardware, etc.

Are you suggesting we bury RG-8 in our gardens? The RG-8X is plenty
good below VHF.

The phone and the CATV are already buried. All the plants care about is
bull****.

Planting your coax at least 12' down can dramatically reduce common
mode noise originating in your home from reaching your antenna!

In repeated tests in the 'real world' and my lab I was unable to
detect
!!ANY!! difference caused by differing coax impedance with many
different receivers.
R2000
DX398
R390
R392
R8B
AOR 7030+
And every other receiver I could lay my hands on.

Pick the cheapest cable with the best braid and that is rated for
direct burial.
An advantage of the quad shield is the reduction of 'transfer
impedance' signal
ingress of MW signals. Very few people will live close enough to a MW
station to
experience worry about this minor problem.

JDaR - To Parphrase : Still 'RF' Runs Deep ~ RHF

Yes - Buried and Burying your Coax Cable
feed-in-line is a Very Good idea :

Four to Six Inches (4"~6") is Good

Eight to Ten Inches (8"~10") is Better

Twelve Inches (12") or more is a whole lot of Work -if-
you don't have a Machine to Dig the Trench for you.
