Completely Banned for the Greater Good
I just bought a 1/4 wave NMO mount whip for 800MMhz stuff when I travel to some areas like Portland OR where pretty much everything is on TRS 800MHz. Anyway, I got a Laird rated for 806-866MHz. The specs say the whip is 3" and by golly it measures exactly that. However, according to the calculation I normally do for wavelength (243/MHz = 1/4 wave in feet) and work backwards this 3" whip is really cut for around 920MHz. For, say, 853MHz I calculate 3.41". Why is this Laird cut so short? I know it's only 0.41" we are talking about but at this band every fraction of an inch amounts to a large change in frequency.
Thanks for any assistance.
