There seems to be some confusion about large and small vertical
antennas on  LF.
Although the radiation patern(profile) is the same the INTENSITITY of
the propogated signal is much greater from the large vertical given the
same power. I have tested this and found it to be the case. There seems
to be some contradictory opinions but they are only theoritical and  I
await someone else to perform a practical field test. ie install a 120
ft vertical with  a suitable antenna resonated for 136 khz , then
dismantle it or lower it to the average 30 feet, re-resonate and check
out the difference. Use the same radial system.
