Topband: Effect of trees on vertical elements?

[Tim Shoppa]

John, your 80M dipole with 110 foot vertical feedline fed as a top-loaded
vertical on 160M is a wonderful antenna.

If you are unhappy with its receive performance,the solution is to add a
receive antenna (or two, or three....!). Not to put up a worse transmitting
antenna :-)
