[Antennas] More Questions on Multiband Antennas

[Kevin Nathan]

Hello All,
 
When I asked my question concerning recommendations for multiband antennas
which I might use to replace my current inverted vee which is 60 feet per
side and fed with window line, the only recommendations I got back were for
full wave loops.  While this is ultimately my dream, I don't have the real
estate presently to put up one of these.  So, I am back to trapped or other
types of antennas.  To be honest, I'm not finding much in terms of dipole
antennas trapped for the WARC bands as well.
 
In conducting research on the net, I keep seeing the figure of 102 feet pop
up again and again.  This, of course, is the length of the classic G5RV and
I have found at least two other references to multiband dipoles for 80 and
up with a length of 102 feet.  Is there something magical about this length?
This may sound silly, but is there a magical suggested length for the non
resonant dipole for 80 and up?  Is 102 feet this special length?
 
I would appreciate any thoughts any of you might share with me on this
question.  Thanks very much and very 73.
 

Kevin :)
