[K3CAL] 2 meter/70 cm Log Periodic Antenna Project...

[Jim Tetlow]

I was under the impression that it was 142 to 450 continuous. Wouldn't that mean 2 meters, 1 1/4 meters and 70cm?  Three amateur bands, thinking that be the case, it was exactly what I was looking for with one coax and no duplexers. If it doesn't cover 220, it isn't exactly what I was wanting, but would still be fun to build........if it doesn't cost more than $60 worth of materials.

>> If you are going to use it on 2 meters, then build a 2 meter yagi.
>> If you are going to use it on 70cm then build a 70cm  yagi.
>> Why waste all the extra elements that are not in the ham band?
>> Better yet build a 2 meter yagi with a 70cm yagi under it on the same boom.

Boom is less than 4 feet... longest elements are 44 inches... we would buy materials in 20 foot lengths... think pop rivets..  drills..... SS hardware... Lexan/PVC........   Post interest.... I will work out $$  cost will be materials only... keeping receipts...Please post Interest.... thanks!   Steve   N3IPN...
