Choose MACO for three reasons:
1. They understand the dB relationship to power gain;
b. their dB isn't relative to TRUE (whatever that means);
iii. it's cheaper.

On the negative side, neither seem to be acquainted with the dBi or
dBd basis of comparison (giving them the appearance of being yokels
selling out the trunk of their car). Imagine, having more "audio
gain" than rf gain from an antenna (do they inluded phased speakers?).

A claim of "2kw power handling capability!" is to suggest this is
part of the gain package? Don't exceed 2kw/28 input power?

Howabout "quad reflector to obtain the best combination of gain and
front-to-back ratio." Why not fully quad design to obtain the best
combination of ALL gains?

What's the difference between FRONT TO BACK RATIO and BACK REJECTION?
