1. Make sure the inverted V is not going to interact and distort the
vertical TOA.
2. Try to at least get a 30 foot horizontal boom on the mast in the
mean time. This will bring you very close to a 1/4 wave.
3. Use a 3 wire cage to make the feed a bit more manageable and
broaden the B/W.
4. A 100 foot standing alone is overall a very good radiator low
angle radiator on 1.8 if the ATU can be perfected.
Good Luck,
