This is a short video with modified the plans provided by ve3elb.ham-radi... for use with copper pipe and a Di-electric insulator. The whole cost was under $20 and alot of fun to do.
time of 5:04 , sir you forgot to put back the black spacer to isolate the SO-239. is it that the center of SO-239 connected to brass? coz you did not mentioned what to connect in the center of SO-239? will please elaborate that portion. tnx 73
the black piece is a washer, this is only used to prevent water from leaking from the fitting. no need to use it because it's not being used for water.
Greg, i was looking at the SO-239 leads you took outside of the nut. Did the center go to the element and the shield lead go to the connecting t-connector & nut (Or Vice-Versa)?
Why on earth would one use a SO and PL connector on 70cm (or even on 2m). The connectors are ok up to 100 MHz. I would rather use a BNC or N-Connector. PD0PSX
Because that is what is used. Every 2m I have ever owned or seen, HTs not withstanding, have had a SO-239 on the back of them. This includes every single dual-band 2m/440 mobile as well.
Works very well. No problem hitting Michigan about 120 miles across Lake Michigan on 2m
Now that is ingenuity, good work.
Nice, good work, simple and effective.
very good idea thanks to you and VE3ELB
that is the rustiest file I've ever seen
this antenna cant work. you have shorted out the so234 and the dielectric connector.
it does and it does work well
How well does the antenna do through your attic?

the center is isolated when the SO-239 is attached.
the insulator goes in before the brass fitting, which helps to isolate the SO-239

Im just working on how the driving element & the copper collar of the isolator is connected to the center coax post of the SO-239
Figured it out. Sorry.
The element went to the center and the shield went to the nut
how did you mount this antenna
what was the pices call that u put the pl259 mount in
Andrew Murphy a dielectric union
how do you mount the antenna?
+jfranke3 Sorry, I missed this. I use a conduit clamp nailed to my rafters in my attic. No problems at all.
