AmateurLogic.TV Episode 4

We're back with the Active Cantenna to finally do some range testing. Thanks to Amateur Radio and a couple of video cameras, we put you right in the action. Ride "Shotgun" with Jim as we test WiFi's advertised 300′ range. We were pleasantly surprised....

There are more great web sites under review in 'Website Roundup'.

Tommy performs a little Digital Photography Magic by producing a 10 Mega Pixel image from a 6 Mega Pixel camera!

PLUS, there's a surprise visit from some other popular IPTV Show hosts.

I am wondering your thoughts on using a maybe 6' bit of 4" aluminum irrigation pipe for the tube of the cantenna. I suppose that the antenna must be added to the pipe and then a cap or plug added to the rear end of the pipe to facilitate easy construction. Just a thought, David in Oregon

I think that would be extremely directional. I'm not sure if you would pass the point of diminishing returns with a pipe that long though.

I wonder how much Tx power that little Linksys has, maybe 200mW? That's some great performance. That gives me great hope for my 3.2 mile WiFi bridge I am planning to get service out to my future home site that has no service. I was planning on using the Ubiquiti 800mW bullet bridgers, 24dBi grid dish antennas and keeping the bridgers within 10ft of the antennas using LMR-400, providing room for lightning protection of course, and running cat5 with PoE up to them. So no other wires to run.

@gthomas if u used this strictly as a TX antenna And had a seperate omni for RX then perhaps but otherwise no go on a pipe that long. if you do this let us know how it werks out

I just found this podcast, and I'm really enjoying it, guys. Keep up the good work!

You ever consider using a 3' satellite TV antenna and recalculating the focal point? Some of those antennas have something like 25 dBi, and I wouldn't be surprised if you could make a good connection at twice your current distance.

Also, ever consider putting that linksys on the ham band, putting an amp on the thing, and staying connected to fellow hams continuously? That should be a lot of fun :D.

you can get some crazy signal distance when you point 2 of em at eachother, or even try the proffesionally manufactured ones...

I'm glad you guys did this clip!  I'm playing around with a plastic collander lined in tinfoil attached to a broomstick inside my apartment-- using the same, but unaltered, linksys component c-clamped to the collander.

tnx,
