Following on from my PMR446 Antenna I decided to try my hand at constructing a 2m/70cm Vertical Dipole Antenna.
3mm stainless steel rod was used for the antenna arms and various other bits and pieces I had laying around in my shed were used to complete the build.
I still need to construct a better designed mast but the one I cobbled together worked fine to test the antenna.
SWR for 2m calling frequency was a near perfect 1:1
SWR for 70cm calling frequency and PMR446 approx 1:1.5 which I believe is acceptable.

Looking good Derek. Homebrew 2m/70cm Dipole Antenna 1f44d 

Once you start building antennas there's no stopping and they'll grow in number until you have quite a collection of them! Smile


Thanks for posting.


All the best,
Victor

Looks great!
I've made a few of these. Work great. I also made a fan dipole by adding a 3rd dipole for 220 Mhz. It was fun to do and use.

Thank you, I've never heard of or seen a fan dipole but I'll now try and find one on using Google or Youtube.

Looks good and I'm sure it tested well, especially when you have it on it's new mast which I expect will be a little higher. Smile 

I have a lot of antennas to build and have been waiting for an improvement in the weather. Now the clocks have changed, we have lighter evenings. So when it stops raining I'll be throwing lots of wire and aluminium skywards.

Looks like a fun build. Getting a dual band antennas in a compact design looks worth the effort. Thanks for sharing the pics.  Wink

I enjoyed the build process and hoped by sharing my photos it would inspire others to have a go at building their own antennas.

Yes Ace, my intention is to mount it a little higher - let's hope the weather improves so we can all "get outside and play" Very Happy

Indeed, it's been a long, wet Winter and time we had some antenna fun and helped the wiggly waves escape to DX lands. Arrow
