RIGGING - The LMZ-75, SWLZ and RF Systems MLB (Magnetic LongWire Balun)
Jason - aka "RF Junkie",
IMHO - You have two products that by design lend themselves to two different types of Rigging and two different Configuration (Shapes) of Shortwave Listening (SWL) Antennas. PRODUCTS = http://www.geocities.com/qrp_baluns/LM.html RIGGING - The LMZ-75, SWLZ and RF Systems MLB (Magnetic LongWire Balun) http://groups.yahoo.com/group/Shortw...a/message/6307 INVERTED "L" ANTENNA : SWLZ with "F" Connector to used with RG6 75 Ohm Coax Cable and Rigged as an Inverted "L" Antenna with the SWLZ mounted directly on (or very near) the Ground Rod. SWLZ = http://www.geocities.com/qrp_baluns/SWLZ.html IMAGE = http://www.geocities.com/qrp_baluns/SWLZ-640.gif HOOK-UP = http://www.geocities.com/qrp_baluns/APP-SWLZ.html ABOUT - Shortwave Longwire Antenna Balun Match 9:1 # SWLZ READ - The "SWLZ" Shortwave Listener's (SWL) Balun http://groups.yahoo.com/group/ETON-E...o/message/1005 http://groups.yahoo.com/group/Shortw...a/message/6034 HORIZONTAL "RANDOM WIRE" AND "SLOPER" ANTENNAS : LMZ-75 with "F" Connector to used with RG6 75 Ohm Coax Cable and Rigged as a Horizontal "Random Wire" Antenna with the LMZ-75 mounted on the House or other Structure abd using the Radio Shack's Ground via the Coax Cable Shield.

TIP - Here is another Product that you may wish to consider. A Feed Line Isolator for your 75 Ohm Products that use "F" Connectors like the SWLZ and LMZ-75 Matching Transformers call it the "FLI-75" ) Use a piece of Copper Pipe for the Body and Plastic End-Caps for the "F" Connectors. Look at this WellBrook Low Noise Antenna Diagram : "The Correct Way To Install A LongWire Antenna/Balun" http://www.wellbrook.uk.com/longwire.html - - - Suggest you do your own Diagram of the SWLZ with a FLI-75 for your Application WebPages. iane ~ RHF . . .. . = = = In , = = = "rfjunkie" kg7ro@j... wrote: I just wanted to clarify a few points on the SWLZ antenna match and different longwire confirgurations: Although the application note shown the SWLZ in an "L" configuration, it is not limited to this. You can attach this match directly to the end of the longwire if you wish. It will require grounding further down the coax instead. The reason for having it at the end of the vertical leg was to get the ground terminal on the SWLZ match as close to the ground rod as possible to reduce noise. There is also the LMZ-75 which was designed to mount right at the end of the longwire. So what this means is that both options will work and the fun of experimenting must be accomplished to know what works best for your situation. There are many other variables at your location that limit or enhance your antenna setup and not one type of antenna connection will work for all listeners. Jason . . ..
