Interesting look at High-Gain and Extremely Long Wire Antennas (conceptual – I haven’t tried these!). Apparently Dipoles and End Fed Antennas do this! Have you tried one? Do you have the space? Give it a go. Of course Beverage Antennas have similar characteristics (but work totally differently) which is why there are fab at RX.
