RW> EH>> I wish I had some trees on my property. All I have a a bunch of RW> EH>> shrubs. The nice tall Doug Firs and Hemlocks are on my neighbors' RW> EH>> properties. RW> RW> YEp, they'd be good for antennas. I've got a couple nice RW> RW> oaks around here. One at the back corner of the lot anchors one end of RW> RW> the 80 meter dipole. GOes to the other end. RW> RW>EH> The electrical service comes in from the front for me... RW>EH> fortunately. It still sucks that I have all that room in my back RW>EH> yard and nothing to hamg an antenna on. RW>Yah that's a bummer. Maybe some stakes, you could always do the inverted ve RW>thing with stakes for the ends possibly. I would if my electrical service RW>didn't come in in such an RW>awkward manner in the rear of my place. Richard and Ed, I just wanted to insert a Antenna idea to Ed. The Metal Slinkys can be used as an Antenna. A long time ago I read a story in a Ham Magazine about making an Antenna using four Slinkys for 80 Meters. I have mine in my attic. My house is about forty feet wide and has a Gable Roof. I soldered the ends of two of the Slinkys together, and did the same for the other two. For the coax connection in the middle, I sawed out three pieces of Plexiglass, I made Square and slightly larger than the Diameter of the Slinkys so I could put them together with 8-32 (eight-thirty two) Nuts and Bolts. Solder the Center Conductor of 72 Ohm Co-ax to one of the Slinky sets, and the Shield to the other set. To make the "Slinky sandwich" I put one rung of the Slinky set between pieces number one and number two. I did the same with the second Slinky set, between pieces number two and number three. That was the way I did it to keep the two sets from touching each other in the middle of the Dipole, You might have a better way, Ed. I would guess a Slinky Dipole using only two Slinkys would work for you on Forty Meters, I've never tried that. My Eighty Meter Slinky Dipole is strung in my Attic. I want to tell You about my Twenty Meter Inverted Vee Antenna also. I mounted the Center Insulator by driving a Nail on the side of the house, just under the Roof, and tieing it to the nail with some Synthetic Cord (String). I used 14 Gauge Solid Enameled Antenna Wire, and put End Insulators on each end of the Inverted Vee. On one leg I used some more of the Synthetic Cord and tiee it to the top of the Chain Link Fence, in front of my home. For the back leg I had to reach around my Brick Home to tie the Cord to the Drain Pipe from the Gutter. I used several Half Knots (also known as Clove Hitches) when I fastened each Leg of the Antenna down. Since I had to string the Cord around the Brick Corner of the Back of my Home, I used some Insulated Electrical Spaghetti, You Know, the stuff that G-C sold way back in the 1960's, that wholesale Radio parts stores carried. I have had an Assorted Bundle of Spaghetti in my shop bench for ages and I don't know if it is avaliable anymore. It might be that Radio Shack sells an bundle of it. I just got finished roaming through the old 2002 Radio Shack Catalog and the only thing I see that looks like what I call "Spaghetti Tubing" is on Page 232, It is "Heat-Shrink Tubing". The item marked (12) at the bottom right of the page, Catalog Number 278-1627 sold for $1.99 U.S. back then. I would think Heat-Shrink Tubing wouldn't work as good as what I used, because it would probably "Shrink Up" in Summer Time heat and not allow the Cord to slide back and forth in the tubing.
