Good day Friend.
I would please like to know, if I put a 20 meter 4 -element Yagi and a 10 meter 4- element Yagi antenna’s on the same mast / tower how far apart – spacing must be between them?, and which antenna must be on top?
Thank you.

I have a 145 foot Rohn 45 tower that has insulated guy wires and it is grounded at the base in concrete. ( no ground radials ) I would like to have a low angle antenna for 160 and 80 meters.
The tower is between my house and driveway and garage, so little hope for underground radials.
I have been reading about end-fed 1/2 wave antennas and I was wondering if I were to suspend a wire spaced about two meters from the top of the tower that was a 1/2 wave long on 80 meters , would there be a lot of RF absorption by the tower ?
Your input is much appreciated

Greetings from California. I was given a home made 6 meter LPY from a Ham friend of mine that is somewhat similar to your design on your webpage. It needs the director element replaced. I was curious from the element measurements that was given to me with the antenna that the director element is about 3/4 of an inch longer than the next driven element. Is this a correct design characteristic of the LPY antenna? Great website.
Regards,
Ryan
I want to operate my home station remotely. A friend recommends IP-Sound.
Home computer is a PC but my remote is a MacBook Pro. Is there a version of IP-Sound for Mac OS X Sierra v 10.12?
You reference some of my earlier work – thanks. More is on my website http://www.jokalympress.com
