attic dipole question

[Whiplash-265]

again, much appreciate the input guys..

i think i might add the plexi insulator back into the equation (thanx 'Doc...i didn't think it should affect things but at the time it removed one possible variable so...), and i'll probably split off the coax into two pieces (i have spare 259 connectors ) and run a second dipole from the back side of the same insulator...i already have a splitter so why not. that way i can cover the lower end of 27 on A and the upper on B

ya, here i go adding stuff to a project i haven't even got right the first time yet

the plexi was "acquired" from work as were the bolts etc etc

i didn't get a chance to get new wire but definitely tomorrow...now if i can get away with only 5 hours of overtime i'm all set

quick question if i might? are insulators necessary at the ends of the wires? or am i safe with a loop at the end of the wire (insulated) and twine leading off to screw eyes?

and oh NB...for the coil i used a roll of packing tape that just happened to give me the 4"
worked like a charm!! coax fits beauty. thanx for the tip

the local skippy peanut butter rep will be so disappointed:mellow:

Those end insulators. I haven't used them in years. I usually make a loop like you said and run nylon "trot-line" cord to the supports. If it get's wet, then don't use the colored stuff, the dye in it can conduct. Found that out the hard way.

Nothing special here, but thought the idea deserved a photo.
As has been done before and started this thread, two mobiles as a dipole. Good SWR across CB band. Doesn't have the ears of the full-sized Omni I run, but it does work. I've made both local and DX contacts with it. I made it for a small travel dipole to use if a larger wire one is out of the question.

thanx for the pics HomerBB

Here's one of my dipole setups

Made this out of a home depot paint stick, left over 14 gage lamp cord, some crimp rings, and some twine. The radiator is away from the garage door track so it's not affecting the SWR, I've got about 1.3 to 1 at the top end of regular 40 channels. Works ok, can hear the highway with the truckers on 19, and if the DX conditions are right, I can work skip into the mid west from my QTH in Maine. Hope this helps. I've got a similar set up in the attic space above the garage and works just as well. Next project is a vertical made out of 2 4 foot fibreglass whips in the attic space in the main house. The condo/home-owners association do not allow antennas outside at all, not even satellite tv dishes!!! 73's

Garage dipole looks good.

Good job. Then put in a backyard lamp post, or bird feeder or flagpole.

Dipole looks great.
The best attic antenna I've done so far is a full wavelength rectangle loop.
