I though they showed a 23db antenna?

That's all USB stuff. Put it behind you, just forget it. Get the new generation kit and enjoy it... you'll never have to install a driver again.

cheers,
Nick.

Now THAT takes one heck of a lot of Chutzpah! Take a $40 usb adapter, $6 plastic box and a $40antenna, mod the driver interface a little and charge $425! JEEZ!

BTW, a 23 dbi antenna would have a beam width of about 9 degrees. You would have to point it exactly at the access point to receive anything. Might be good for establishing a link to Virgin Gorda if you are marooned on Sombrero Cay but pretty useless on a boat.

And now a voice from the wifi wilderness:

Once again the M2HP has a usable wifi signal from the topping lift, just above the main boom on a 8-9 (I must take a close look soon) omni. Just not getting it with the 2HP at the masthead with the big dollar 15dbi antenna.

This is at Fox Town on Little Abaco. You can't anchor very close to town here.

At Green Turtle Cay there have been usable signals in the morning and the evening but during the day it's just too much other noise. But with the cantenna and the M2HP we cut through all that. Just knock the power down until it won't work then put back just enough dbs.

We used the Masthead 2hp on the way in strafing the coast and marking alternative anchor locations as we approached New Plymouth. Now hooked into one of the Restaurants on shore with a nice fast connection. And we are furthest anchored out here.

We have a slightly larger can that I'm going to be testing soon from a cranberry cocktail can. It will of course be the "crantenna". heh heh

Very Cool! Good on you for the innovation. Do you have it patent yet?
Oh... and whats that other gizmo behind you and to your left with the crank? Another invention? I love inventions!

Cheers,
Extemp.

Cantenna...it's what I've been saying since the beginning of thread. I've designed and built 5 of them so far..one for a cruiser.

Built one for my Commander over in Kuwait so he could have Internet.

However, anyone looking at these, it is not just drill a hole in any can and "pow".
There is math, measuring and specific lengths of radiator depending on what frequencies you want to use it for.

Yeah, and there's still money in the pocket of the pants hanging to dry there! Hope it didn't go through the crank-thinghy however you call it in English (if it's "wringer" like Google translate says then it's another Dutch word used in English

cheers,
Nick.

I like the picture, but what does the connection look like.
Can you take a closeup?

[thatboatguy]

Right... well I'm no mathamagician but I started with plans from the internet somewhere and started tweaking. My neighbors are used to me poking around in their recycle bins by now...

I'll try and remember to take some better pictures tomorrow. Just got back from the best conch dinner ever at Laura's Kitchen and I'm feeling like hibernation might be near. Essentially the connection is an N type panel connector with a 12 gauge solid copper wire radiator soldered into it.

Yes indeed the thing with the handle is a laundry "wringer". With the starboard side cockpit table down I have a five gallon bucket that it's attached to strapped in place for Kerri to do laundry. A 40 GPH watermaker (dubbed the Frankenmaker by friends) I built does not go without use on this boat and we are always clean and have clean cloths. I also "invented" the solar and wind powered cloths dryer you see in the photo.

Here are some close ups of the cantenna.

Yesterday with steady strong winds it was the bomb. This morning having to go up and re-aim it every 5-10 minutes... not so much. But hey, it's better than no internet and I have other fish to fry today anyway.

thatboatguy,

That "cantenna" is just amazing. Looks so simple.
I can't believe something like that would work, but you are living proof.
Very glad you shared it with us. Don’t tell me, tomato cans work the best.

Just trying to set up the M2-HP and I can see the access points when I use the drop down tool but no way to connect there. Do not have the tab "link setup" that you all are referring to. Instead I have a tab called "wireless". Any Ideas?
