At 27 MHz, any antenna shorter then 5 feet is a waste of time.

Not true. There are antennas at five feet that will match or even
surpass a 102" SS whip.

Bull****.

This has been shown before. Get off your fat ass and do an actual
test. You will find that a Stainless Steel 102" whip can be marginally
beat. You can not realize this by reading a book! Get off your ass.

P.S. A 1/4 wave whip of thicker more conductive material can't be beat
by a shorter antenna, but my comment was about the common 102" SS
whip.

Using Mmana to simulate antennas;

The difference between a 5' and a 8' copper antenna is 0.3 dB

The difference between a 8' copper and 8' stainless steel antenna is
0.6 dB

(by the book) a 5' copper antenna will beat a 8' stainless antenna.
