Center Fed Dipole

Post by VA3GPK »

Watched the video for the Linked Dipole that was posted by DL2MAN and thought that the Linked Dipole was something that would be of use to me. The measurements for this dipole are on the antenna page for this site along with a video. With very little tweaking this antenna for me was close to bang on. I say for me since we all have something that may not be exact to the others. My results at Centre 21' high (6.5M) and lower end 4'(1.25M).


80m 1.18@3.640
60m 1.09@5.390
40m 1.07@7.100
30m 1.11@10.170
20m 1.20@14.180

I used a plastic cutting board to make my center hanger and linked insulators
used 24 Gauge Silicone Wire Ultra Flexible High Temp 200 deg
Insulated Male/Female Bullet Wire Connector, Ring Connector
SO239 Chassis Mount

The antenna does work no issues here. Jumped on the air this afternoon to put it to use and prove itself.
Many operators complaining about band collapse and solar flares. 5 POTA contacts and 3 individual surf contacts has me convinced that the antenna is fine.

Thanks for your feedback.
I also have the impression, the linked Dipole does work great.
I made a spontanous COTA/WCA/WFF activation on Sunday with it, and even though it was un-announced, I was cluster spotted, so I ended up with 19 QSOs on "dead" Bands to obviously Germany, Poland, Romania, Sweden, Israel, Finland, Ukraine and even USA. Those were on 40m and 20m.

This is a pic of the RBN Spots of my activation:

The main advantage is: Opposite to EFHW, at the linked dipole, the low impedance point (=where max current flows = where max radiation happens) is always at the highest point.
