I don’t know what the value these patents are or who will put a value on them. Let me ask you this, who owns these patents and point me to that bit of info. Looks to me as if someone other than PMPG owns these patents.
Patents for ideas that do not work are not very valuable. Still sitting out there is the need for a very small photovoltaic cell to charge a very small battery capable of powering these turtles to 100mW and sustain this transceiver operation for an extra 24-48 hours if the weather is overcast.
After that is worked out, then come up with a solution for the horizontal oriented antenna in a vertically polarized digital world. There is a 25 dB mismatch loss in which I just described.
The photocell/battery I just described has yet to be created by man on this planet.
