- Ham Radio Outlet sells the good stuff by the foot ( RG6 vs RG8X) - - 5) Manufacturer: BELDEN - Item : RG-8X - Description : #9258 MINIATURE COAX - YOUR HRO PRICE $0.69 - Additional information : - Sold by the foot - please specify quantity - up to a max cont length of - 1000' - Stock status: In-Stock-Item - - http://www.hamradio.com/cgi-bin/uncg...elden&MAX=250& - David, The BURY-FLEX (TM) that is offered by the Davis RF Co. is also pretty good stuff too. ~ RHF http://www.davisrf.com/coax.php#buryflex -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. iane ~ RHF |
