I'd eliminate requirement #3. Then, I'd put up a 100' doublet, and feed
it with open wire or 450 ohm transmitting twin-lead. Run the open wire
right to the house, then use a balun before going inside. Use the
shortest possible run of solid dielectric RG-8 / RG-213 to get to the
tuner. Some transceiver auto-tuners can handle this antenna directly.
100 feet is a bit too short to cover 1.8 MHz. But, as long as it is high
enough, this antenna will do OK for the other bands.
