Assuming you can tolerate a 3D structure, doesn't a two element 40M quad
make more sense? I am using one and EZNEC models show the three element
full sized Yagi only 0.2 dB higher gain: 7.7 dBi vs 7.5. It only
required a 20' boom and it's a 30/40M duobander.

It will bring you great satisfaction whenon the air.True - but you can have as much fun for a lot less. IMO a comparableif not better system is to stack two 2L shorty forties. Lots cheaper, comparable gain, choice of upper or lower antenna, ability to beam 2 different paths and you only need regular rotators to turn them.A local guy built a full-size 3L 40M beam and (this was years ago) themiddle chunk of aluminum for the boom was 300 bucks. Can't imagine what the total price was. Don't forget to throw in a couple of grand for a prop pitch to turn the thing.Cheers,Steve K7LXC TOWER TECH _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.com http://lists.contesting.com/mailman/listinfo/towertalk |
