[Antennas] Hustler 6BTV Vertical vs. Monopole?

[JAKidz]

Greetings:
	What is the loss / radiation efficiency of a Hustler 6 BTV
trapped vertical on 40 meters compared to a 34 foot monopole on 40
meters, both mounted at 11 feet with 4 resonant radials? I've found
estimates from 1/10 dB per trap to 7 dB, ignoring the inefficiency due
to length. If it's 4/10 of a dB, I'll go with the Hustler. If it's 7 dB
or more, I'll probably build something along the lines of N2NL's or
K7ZB's "stealth" verticals, providing I can make it stiffer than K7ZB's,
so I can tip it up on use and down to change bands and hide it
otherwise.

Thanks and 73,
John, K7JG.
