Put up 66 ft of wire, or any length that is convenient. Wire length is
unimportant. Inverted vee is ok. Feed it with open wire line (Or 450 ohm
ladder line) an any point you like. It will work just the same as a full
sized dipole.


EZNEC says that a 66 ft dipole used on 3.8 MHz, fed with 450 ohm
ladder-line, will have an SWR of greater than 100:1. This can
lead to all sorts of undesirable effects including an almost
impossible to match impedance at the tuner. A practical rule of
thumb might be in order, e.g. mine = no more than 20:1 SWR on the
ladder-line.
