If a few inches length matter . . . or if The Look gets in the way, then:
IDEALS:
| ANTENNA LENGTH | EXPECTED RANGE |
|---|---|
| 2 feet | 2 to 3 miles |
| 4 feet | 4 to 6 miles |
| 5 feet | 5 to 7 miles |
| 102 inches | Up to 10 miles |
7 feet is 7 to 10-miles.
4’ & 7’ not in the same class.
(NMO27 vs SIRIO Performer).
A max six-mile radius (4’) is 115 sq miles.
A max ten-mile radius (7’) is 300 sq miles.
Change antenna length by 1-2’ and coverage changes which is significant against heavy metro traffic even where the distances above aren’t in play given how poor are most radio rigs (generally).
That aside:
NMO27 at 4’ @ 50 sq miles (Metro) vs NMO30 (W640 whip) at 5’ @ 80 sq miles (Metro) would be interesting compared for this very reason. Does one hangs on noticeably longer? Enables more contacts or Q&A in heavy traffic?
I couldn’t say that a few inches length matter, but a foot or more . . from experience, yes, it does.
If it’s brand/construction I can’t see a reason to go with the cheap brand. A year or more past purchase no one remembers the extra, only if it’s still like-new.
