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.
