update them using techniques that weren't even dreamed of in the days that these
units were designed.
And yes, I am fairly well known for VHF stealth (hidden) antennas in plastic
structures. However, when I do *not* know the answer to a particular question

a cardioid is an art, as opposed to the theory (which has been well known for
almost a century).
shared these priceless pearls of wisdom:
