Hi Richard,
It may look good to you, but for many it remains sloppy.
The convention of ASCII-Doodles is to employ fixed pitch fonts. This
is available to everyone.
A, spacing between bottom of the discone and the boom of 2 m yagi.
0.5M to 1M
B, spacing between boom of 2m yagi and boom of marine band yagi.
0.5M to 1M
C, spacing between boom of marine band yagi and boom of FM yagi.
0.5M to 1M
D, spacing between boom of FM yago and top of rotator.
0.5M
Proximity is more likely to disturb the depth of nulls than to rob
gain. Proximity will also pull resonant frequency. Recommendations
will run the gamut where a purist would demand 1 to 5 wavelengths.
Practice often accepts much less when offset by sweat-equity (more
tuning and trimming on your part).
Don't forget guy wires to preserve the mortar (its not the brick that
breaks); and don't forget to break up the guys to prevent their
resonance effects (or use non-conductive guys).
