Default If the ideal lenght of an antenna is 1/4 Wave lenght then way are the Car Cellular antennas are longer then this ?


Richard, I thank you for your time and trouble expended in trying to
educate me regarding the field strength from a 1 Kw transmitter at a
distance of 1 Km.

Your efforts, of course, will not be wasted on other readers of this
newsgroup. Very good stuff!

But you have misunderstood my attitude towards this discussion.

As I have said before, amateurs and professionals alike, all suffer
from delusions of accuracy. The uncertainty in prediction of field
strength of groundwaves can amount to 10 or 15 dB or even more at
extreme distances.

When I say my program correctly predicts a field strength of 300
millivolts per metre at a distance of 1 Km from a 1 Kw transmitter,
nobody can disprove it. Even the 'bibles' state it as a matter of
fact. But we all know how much faith can be placed in 'bibles'.

To be of use, all measurements should be associated with an
uncertainty. Only then can the originators be judged to understand
what they are waffling about.

Thank you for your interest.
----
Reg, G4FGQ.
