Subject: Re: [TowerTalk] antenna material 40M
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.
