I’m currently writing an article outlining the characteristics of the Mega Loop antenna we use for Dorridge Scouts. If you would like a preview of this white-paper, please let me know.
The XXT Mega Loop is the name given for the application of a horizontally mounted delta-loop that has known gain dependant on wavelength size and height above ground.
At quarter wavelength above ground and above, Mega-Loops start exhibiting gain that is proportional to its wavelength and height. A whole series of articles is currently being written by the author, however for the time being, these few articles may help you determine how we operate the Mega-Loop at Dorridge Scout Group HQ.
More information can be found at the following links:
The basic 80m loop:
Firing supports over trees:
The 160m Loop
Some photos of our implimentation of our Mega Loop can be found here:

Don’t worry, I’ll fix this during the week. I changed some picture gallery directory names so that Google could spider the site properly. The consequence is that around 180 articles are now broken. Grrr. I could put the names back but then my Adsense program wouldn’t work as well.
Hang tight :)

I renewed our Narrowboat Insurance on Friday for £450. The broker happened to mention that narrowboaters historically had very few claims.
He said that I had to bear in mind that in the main, mild steel at 2.5 knots bouncing off other steel boats (or concrete) rarely does any damage. Most claims are for total loss and in the main that’s fire. Do you have a fire alarm on your boat?
I also checked what the policy would pay out if we really did end up in a total loss situation and he confirmed that it would pay out exactly the figure we had on the policy. Good.
Now then.. how did a narrowboat manage to end up on ther M6 north of Leicester? Easy, it fell off the back of a lorry. It really did. I found the article on the BBC website.

At last, some advertising on my site which I’m fascinated with. I am seriously not expecting to make any fabulous money off this but with nearly 4,000 unique visitors per month, maybe it will pay for the odd meal out with the family!
The reason for the title is to encourage Google to place the right adverts on their ads. I don’t specify the ads, Google does by trawlering the content and working it out for itself. In the main, the ads have been more or less correct but there doesn’t seem to be any Amateur Radio adverts out in the market. Maybe when the big Yaesu, Kenwood and Icom suppliers actually advertise with Google, I’ll get the ads coming through on this site, who knows.
In the meantime, I’ve enjoyed cutting some code and placing the ads in the right place this morning!
{later: I seem to be making about $6 per hour. This is way cool!}
Cheers from Solihull,
Callum.
