Dave & BpnJ, It has always been my humble understanding : That a Multi-Stranded Copper Wire where each of the Strands has a very thin clear coating where each of the individual Wires is separated from the others is better than a single (1) Wire of the same relative Size {DC Current Rating}. "The Trick" is to get all those separate and individual Stranded Wires in the Bundle to be 'connected*' "Together" at the Fed-Point of the Antenna. {Joints} * Usually this is done by Soldering the Wires all 'together' as one; with the Flow of Solder forming an Electrical Bond between the Wires. Soldering remotes the very thin clear coating and allows for an optimum joining of the Wires as one. Note : Crimping the Wires and other mechanical means of fastening the Wires will always be something less than the Maximum 100% Standard that Soldering the Wires can achieve. -if-all-are-done-right- For the same relative Physical Size Wire with the same DC Current Handling Capabilities a group of Stranded Wires will have more 'collective' Surface Area for RF {Surface} Current than a Single Wire. -roughly- * 1 Single Wire to 7 Multi-Stranded Wires ~ 2X : The Same DC Rating -but- Twice the RF Rating * * Six Wires around a Center Wire * 1 Single Wire to 19 Multi-Stranded Wires ~ 4X : The Same DC Rating -but- Four-Times the RF Rating * * Twelve Wires around Six Wires around a Center Wire IMHO - For most average 'typical' 30 Feet to 120 Feet Shortwave Radio Listener [SWL] Antennas an Insulated Multi-Stranded Cooper Wire makes for a Good Durable Long Lasting Wire Antenna Element.http://www.davisrf.com/antenna-wire/...s/5/fact24.php -however- for Non-Typical SWL Antennas from 150 Feet and up Copper-Clad-Steel (CCS) Wire may be the better option for Extra Strength and Durability in a Long-Larger SWL Antenna.http://en.wikipedia.org/wiki/Copper-...able/wire.html * See #511http://www.thewireman.com/antennap.html -about- Shortwave Radio Listener [SWL] Antenna Wirehttp://www.davisrf.com/antenna-wire/index.php there you have it : 'my-opinion' - iane ~ RHF *. *. Thanks for this. Do Flexweave and the product sold by Universal have this thin clear coating? |
