    Thank you for this video. I know it took some time to film, edit and publish. I am just getting into 6 meters.and this project is right up my alley.
    All the best

    Hi Eric, the wire can be 16 or 18 gauge speaker wire. It is a tight fit to secure the screw. Have fun with the project. 73, N7JFP

    I used a rubber grommet I had left over from a copper tubing project. Find one that fits, trial and error method. It worked great. Good luck on building the antenna. 73, N7JFP

    The 440 band is about 13 inches for a 1/2 wavelength. 6.5 inches per side.
    Each side will collapse down to about 13 inches. It would work on 2m but not 70cm. 73, N7JFP

    Yes. 144MHz is about 20 inches per side. The antenna will collapse down to 13 inches. Give it a try. 73, N7JFP

    Love the video, will be making my own soon. I'm a OTR trucker and was looking for something portable. This would have been a lot of fun during those 3 day layovers in Nogales, AZ. I love that it can be switched between 2m & 6m with no mods other than adjusting the length of the extensions. Will definitely experiment with this antenna using a painter's pole to get it up in the air. For the guy asking about 2m operation, I'm sure it will work but you want to get this thing vertical for 2m FM. As for a matching network, wouldn't a hairpin match be sufficient?

    I could never find the right grommet to hold the hex coupling. So in a pinch I wrapped it with black tape till it fit snugly. Then JB welded it. Seemed to work good.
    Antenna turned out nice. Thanks for the video. Wondr if this could be tuned on 10m, also?

    • @steveweiss3552
      @steveweiss3552 10 років тому

      It's more expensive, but.... You could scale up this project and use those HUGE 17' telescoping whips (also 3/8" x 24 thread) that MFJ sells (MFJ-1979) for an overall maximum length of 34 feet.. Or forget about building the center box altogether and use the MFJ-347 "dipole maker". You can adjust the the whips to work from 6M down to 20M! Only issue is drooping of the telescopic whip elements. That can be remedied by extending the mast above the center mount and using 1/8" paracord to support the ends of the whips. All kinds of cool things you can do!

    • @ShipWreck54
      @ShipWreck54 8 років тому

      +Mark Pope You can do 10 meters by using those 102 inch stainless steel whip CB antenna's and just cutting them down a few inches for the 10 meter band. Will have to mount everything vertical or figure out a solution for drooping if horizontal. But those whips screw right into the hex coupler with no mods.

    Hello great video from what i saw, like the improvements to the design. I wasn't able to watch entire video, you may have answered this, but does the distance between the antenna elements make a difference? Is that why the guy you got the concept from used a smaller electrical box? Thanks! And 73's DE KK4MND

    • @N7JFP
      @N7JFP  11 років тому +1

      By adjusting the overall length to 1/2 wavelength and tapping into the middle, the length of the separation at 1/4 wavelength doesn't seem to effect the resonant frequency. The larger box was for easier access for connections. 73 N7JFP

    I am confused, what matching is there from the 50 Ohm coaxial cable to the dipole.
    If there is no match the impedance will be strange much like the polar pattern.

    • @N7JFP
      @N7JFP  9 років тому

      Myles Nicholas The impedance of the dipole is about 72ohms. It is close enough match to the 50ohm transmitter output. An antenna matching unit should bring it in to 1:1. Thanks for watching. 73, N7JFP
