Antenna for my Kenwood R-1000 receiver?

@sp6iad.superfeed.net:
If the short antenna is matched (i.e., you use a tuner) it will be
nearly as efficient as its longer counterpart. A short vertical antenna
has very HIGH current at its base. Any loss in efficiency is due almost
exclusively to the tuner when operated over seawater. Over land, ground
losses become a more significant factor in reducing efficiency.
Any antenna shorter than 1/4 wavelength has HIGHER impedance and LESS
current. It NEVER has high current at its base. It also suffers from
having so poor an H-field generated without that big current lobe.
A shortened antenna is NEVER anywhere near as efficient as a full 1/4
wave radiator....or more...working against a ground system. Boy, would
AM broadcasters love to have an efficient 50' antenna tower. You'll be
FILTHY RICH if you can make that work!...(c;
If you think running your HF tuner is efficient, you are sadly mistaken.
That tuner is simply a big dummy load on a short whip. It sucks!
