6 Meter Portable Dipole - N7JFP



A list of parts needed is at 13:28 of video. This video shows how I made my 6 meter portable dipole using collapsible antennas and PVC. I used a MFJ269 to do SWR testing. To center the hex coupler nut and to keep the epoxy cement contained I used a rubber grommet around the coupler nut. A length of 51 to 52 inches per side will enable a usable SWR over the entire 6 meter band. Now if the band will just open up so I can try JT65 mode on it. 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.

tyvm for sharing. :)

very nice antenna 73's from brasil

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?

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

I made a 6 meter beam from an old CB beam. Works well!!

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

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

Check the end of the video at 13:28 for a list of parts. 73, N7JFP

Any chance can you give me a list on what 2 get im going to try to build
this...

Is there a parts list available?

Автор Leon Eady Jr ( назад)
Thanks for the prompt response!

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

Could those telescoping whips be adjusted for 2 meter operations?

Автор Jon Benavides ( назад)
Actually I feel stupid, I asked that question when I thought the viedo was
over then you showed the bill of materials! Actually they are now 18.00 +
S&H Thanks for the response!

Hi, do a Google search for Buddipole telescopic antenna. They are 12.00
each. They work nice and come in black. 73, N7JFP

Nice job on the antenna.. where can we buy those telescoping whips?

vy nice indeed.

ok cool thanks so much i dont have my call yet but 73 :)

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

hey i am new to ham radio waiting on my ticket to come in the mail i am
wondering what kind of wire you used to connect the so-239 connector can u
just use any kind of wire i like the antenna and want to make one but i
dont know the wires you used to do it ?

nice video and info thanks for Video and Time.

Nice video. Thanks. 73. PU2CLR.

Right now I have HF equipment. Someday I would like to have a VHF/UHF
transceiver. A 2m/70cm dipole sounds like a another fun project. Thanks for
watching. 73, N7JFP

Автор alzathoth ( назад)
really love your antenna build videos. any chance you could do one for a
duel band 2m/70cm dipole design?

Автор wb5rue ( назад)
Did you use anything to seal around the SO239 connector?

Автор wb5rue ( назад)
I knew there was a reason I saved all of that PVC from when I re-plumbed my
house.
