I have the big one like what they had at 6Y1V. It is not made anymore.
It is 70ft across straight elements. Full sized on 40.
The DB42 is called the MonstIR but it's not the actual, original MonstIR.
The original MonstIR posts better f/b figures on 40 through 15 than
even the DB42 but slightly less gain. It is a nightmare for weak
rotors, towers and masts, all 267lb of it. However it has none of the
hairpin sweeps that can collect moisture and freeze up and also no
relays.
My antenna has a 34ft boom.
