I agree with Frank.

So far any physcally short antenna that I have modeled or experimented
with has been found to operate in a manner that is poorer than that of
the 1/4 lambda antenna. The physically shorten antennae that I have
seen that does not lack in efficiency is the tuned small transmitting
loop. This antenna is less than 1/4 lambda in circumference and
actually when tuned will be around 98% efficient. It has very low "Q"
and an extremely small VSWR bandwidth. All other physically short
antenna, less then 1/4 lambda, all have poorer efficiency and lower
VSWR bandwidth as compared to a properly installed 1/4 lambda.
