Another thought.  How about a 40m whip.  Mount it on a pallet and weigh it down with cinder block.  I think hi tuner will match down to 8'.  Use the metal roof as a counterpoise.  Should be almost invisable from the ground.  The pallet would spread the weight out as to not damage the roof.  Just a thought.

Every mobile home has more than enough room for a 100m long zig-zag antenna 1m above the metal roof, but .....

Thanks a lot for the make/model.

It turns out that Ralph is limited by his park management and does not have the space for even a 40 end fed.

Hi Fred:

I think mine may have been the other you scanned.  It was a Par End Fed 40/20/10.  It was a qrp antenna.  I've worked into Europe with it on 3 watts, SSB.  It helps to get it as high as possible, of course.

I currently am using an 49:1 balun from Balun Designs with a 134 foot wire attached.  It resonates on 80/40/20, and tunes easily on the higher bands.

Thank you for the memory jog. I am pondering a better solution to Ralph KE0AJE's mobile home park location than his current Comet mobile HF antenna so he can work the whole world. Implementation is subject to park management veto of course.

Good ideas. I have had the zig zag work well. Also, a group called Spiro used to sell a shortened dipole. If he has an auto tuner, it might be able to end feed half of a shortened dipole. wes ab0se

Podcast of Possible Interest on Numbers Stations

John W. Smith
 

This week's Twenty-Thousand Hertz podcast is about numbers stations, particularly the buzzer, a cold war hold over from Russia. The show spends some time at the beginning introducing listeners to what shortwave radio is. Then they get into numbers stations and the buzzer.


Though there are fewer numbers stations, some countries still find them useful in the 21st century.


Here's the link for the show notes page and where you can listen.

Wow, Fred, Thanks for bringing that one to my attention. Dr. Monica Gandhi was fantastic throughout the whole hour. The way she authoritatively answered those  detailed questions was remarkable. I hope they can use her ideas for the future as she said " we need a referendum on our response" to this pandemic.
