Hi Ted,
Am new to stumbling and just now received Fed-X from FAB with all the goods to get started...
I have a 'hole' here in the spectrum as far as test gear and sig gen., power meter, etc. but am looking through the surplus houses for some. A simple ham type down converter will do for the AVCOM spectrum analysis, Some reworked sig gen and test gear can be built up as well. I am looking forward to seeing the stumbler program working and to see if a 'signal strength' meter is part of the package to judge relative gain.
Am having many ideas as to innovations and improvements and will post them here as they happen.
As far as the 50 ohm termination goes, at these frequencies you shoot for a target then usually spend some time 'bending' and 'pruning' with the help of a VSWR meter.... A simple low per version should be possible to build for a few bux...
Here are some good sources for learning antenna fundamentals and construction. The 2304mhz. ham band and the 2400mhz AO-40 ( amateur satellite ) band articles are worth a look.
Try

Right now am hoisting a grid antenna up on the tower with bi-directional amp. all store bought and out of the box.
Next antenna to try for getting out of ones back yard is a 5db omni with bi-directional amp all mounted in a PVC cannister and hoisted up into the high pine trees with the aid of a compound bow and counterweight.
This stumbling is getting the juices flowing once again...

*Here is a thread on a local bbs that shows some basic ham type wireless. One is on 144 mhz. which is too low for us and some laser work which is too high... Now to 'focus' on 2.4 ghz.
