Re: Balanced vs Unbalanced
I personally prefer the 1/4wave ground plane compared to a dipole. But as Tec has mentioned I've tried a J-pole (broadcast version) made by sandpiper antenna (which they no longer do- unless you shorten the 70mhz one) and that worked very well!

and whats more worrying is 1500 watts through an SO239 Connector? toastie
Im guessing tecs used them just to show you what he can make.

Re: Balanced vs Unbalanced
You’re probably better off using an N-connector. An SO239 will probably be ok, but been told they’re built for lower frequencies.
I personally prefer the small BNCs but that’s a different story.

Re: Balanced vs Unbalanced
We always considered the SO239 to be an audio connector. They're useless at RF!!

Re: Balanced vs Unbalanced
On the wikipaedia page for the SO-239 it says "The UHF connector is a World War II or earlier threaded RF connector design, from an era when "UHF" referred to frequencies over 30 MHz." Sums it up perfectly. In fairness I think the SO-239 is a victim of its own success, it is much more popular than the N connector on American ham radio equipment, so there'd be a whopper factory in China making them out of recycled spitoons and smokers snot.

Up to a few hundred Watts I use "N"-Types. I've even had these melt at 900W!
