Rick, you'll just about be able to get that antenna up if you do an inverted v
since if you're at 30ft in the center the ends will need to be in the 10-15ft
range or so as I understand it. You'll have a problem with a mast that tall if
you can't do something to hold the thing up. A tree would be good if you've got
one.Also, as has been pointed out, keep that ladder line away from metal. If
you're using 450 ohm rather than 300 ohm it'll be easier to attach the line.
