News until 0515, RA "Waltzing Matilda" bridge mx, into vocal mx in Indonesian. Weak to fair. (Icom R75, Mike Bryant, Louisville, KY) Pretty decent that time of night. *What antenna do you use? I live in a community where external antennas are prohibited. But, that log used an external of 80' of wire hidden on the inside of the wooden privacy fence around my patio. I have several hidden externals that do pretty well, particularly with the preamps on the R75. Right now, I'm trying to lay a 100' foot external around the foundation base of my home. Mike Bryant For a 'stealth' Fence Antenna use 300 Ohm Twin-Lead as a long thin Loop Antenna. Build a Nailing Tool to mount the Twin-Lead Small piece of Wood that is 'notched' to Center the Twin Lead in it; with a Groove to Locate and Center the Nail between the Outer Wires of the Twin-Lead. "Jig" Nailing Tool for Twin-Lead [End-View] ==== - Side 3/16" ~ 1/4" == - - - Notch 3/32" ~ 1/8" - - - Center Nail Groove == - - - Notch ==== - Side [Top View] ====================== ====================== ====================[ * - Center Nail Groove ====================== ====================== -note- Centering the Nail is important so that you do not damage the Twin-Lead Wires; and the 'Jig' also helps to keep the Head of the Nail about an 1/8" away from the Wires. *The Nails mainly keep the Twin-Lead 'on' {Attached-to} the Fence and the Twin-Lead taught between the Nails. *Place the Nails about every 6~/8 Feet and at corners and bends. *Some may prefer to use short thin Aluminum Nails over Galvanized Steel Nails;http://www.buy.com/prod/common-alumi...id/88467568/lo... and others may choose to use Aluminum Roofing Nails with Washers which are a bit to big {thick} for my taste.http://www.greatnorthernmfg.com/al_r...ithwashers.htm Matching : Use a TV 300 Ohm to 75 Ohm Matching Transformer between the Twin-Lead and the RG-6 'Quad' Coax Cable.http://www.radioshack.com/product/in...ductId=2103912 Connect the Far-End Twin-Lead Wires together so that the Twin Lead forms a very thin Loop Antenna * Note - Some put a Open/Closed Switch here at the Far-End to be able to switch between the long thin Loop Antenna and/to parallel twin wires {Linear Dipole}. *While others put a Switch at the Mid-Point of one of the Wires to be able to switch between the long thin Loop Antenna and/to one long half-folded back wire plus one short wire. Mount the Twin-Lead toward the top of the Wooden Fence; about 4~5 Feet above the ground. This is a very 'quiet' Antenna; and you will swear that there is nothing 'there'; until you tune-in a Station and it seams to Pop-Up out of the nothingness. iane ~ RHF *.- Hide quoted text - - Show quoted text - Thanks for the suggestion, Roy! I guess you have met this week's quota for useful SW info! ;-) Mike |
