How was the match?

It is tunable, when building it you need a small variable cap that is used to tune the antenna to what ever frequency you are using.
Once the antenna is built, hook it to your radio, dial up on the band that you built it for, listen to the RX and tune the Cap for the most noise...I was surprised, that point also was very close to a point where SWR was usually less than 2:1
Go to the Page where Alex has his antennas and one of the videos shows him deploying his loop, and how to tune it.
It was a project i played with for several weeks, then moved on to making a Balun and loading up a downspout and a rain gutter for HF work....
It is a terrible thing to have ADD....hard to stay focused on one project

No one would ever accuse me of such a thing. . .

The Up side to that Homer is you get to cram more projects into the day......the real hard part is getting them finished LOL

Did you have a look at the links to the loop antenna I had posted?
It was a fun project to play with.
I thought that WD8PUO had a nice home brew loop going with the sliding "Piston type" match, another way to tune the antenna, and they work well for the size, here is a quote from KR1ST`s website:

I'm a QRP operator and never use more than 5 Watts (SSB). With the antenna in the living room and at this power level I've been able to work Europe, Asiatic Russia, the Caribbean, South America, North America, and West Africa. I have been able to work over 80 countries with only 5 Watt SSB and this antenna.

They make fun portable antennas for rigs like the Yaesu FT 817, FT 857/897 or the New Elecraft KX3.

Your certainly right Audio, this weekend i thought i would work on two antennas, a 2 meter ground plane and an eleven meter as well as get my trailer ready to go and pick up a tower i am buying used...well i spent most of the weekend working on a leaky faucet ( i thought was just a gasket) but turned out to be one complete replacement of valve and line portion. rust and calcium deposits suck!

Someday i would like to try one of those loop antennas for fun.

AS, I glanced at them, but will go back and read/look closer. I'd like to try such a thing.

Hey Homer. Did you ever complete that dish antenna?

The diameter of a dish needs to be multiples of the wavelength for which it is used.

My Old summer home...
We had a 30 foot concrete C band dish.

Bet that would have made a killer 1.2 and especially for WiFi antenna
