2 Meter Slot-Cube Antenna (QST Jan 2019) K1AWC on 17/4/19

Using K1TGF's dimensions, the new one I built came out resonant enough in the 2 meter portion with an SWR of 1.4 at 146.500 mhz which is just fine by me.

Also, instead of screwing in the feed line to the stubs, I used 3/4in copper pipe strap and wraped it around the 1/2in stubs and secured it with a bolt (if that makes sense).

KC6ZBE, your initial resonance at 152Mhz is a LONG way off from the ham band. Did you readjust the size to reach resonance on 2 meters? if so, what are your final measurements?

Thanks for your help guys! de N7LT

Sorry for the late response, OM.

I see a lot of other people got their cube resonant somewhere in the 150mhz range as well with the original specs.
I tried the heating up/hammering out method but gave up. I decided to try to make a new one using K1TGF's dimensions. I like the idea of how he added some length on some sides.

Got a few more pieces to solder and we will see how it goes.

Started to build this yesterday and noticed it didn't "come together" as specified in the article.
Glad I found I wasn't the only one!

Finished the antenna today with the updated dimensions and I am resonant at 152.4 mhz. Checking the 2 meter portion gives me a SWR of 4.2

It was a fun build, but just curious how your guys' cube came out.
