I'll take 5, if you decide to order a bunch. Let know when to send $ to you.
I have used the one I have as a signal source for checking 10-meter
antenna F-B ratios. Mine went into a plastic box with a battery, switch
(power), and a collapsible whip. Put it in a tree 10 or more wavelengths
away, turn it on, go back to the shack and check S-meter readings over
the 360-degree sweep (and back again, in case the battery is getting
weak--which it hasn't in a year of off-and-on use). Signal is clean to
the ear, but have not scoped it--there may be a difference between light
and heavy loading. But a tiny output filter ought not be too hard to add.
