used on the 72mhz band were 1/4 wave antenna’s. Approx 1 m. The

4.8in. So an equivalent quarter wave antenna will only be about

style="FONT-SIZE: 11pt; FONT-FAMILY: Calibri"><BR> <BR>Basically, the
length of the antenna is related to frequency of the transmission. 2.4 gig
freq is made up of small wavelength. If you remember High School Physics, the
relation between Freq and Wavelength... ie- it's an inverse relationship. As
Freq goes up, WL becomes small. At 72 meg, WL is fairly long, hence the reason
for the longer antenna; at 27 meg, wl is even longer. Those who used 27 meg
equipment a bunch of moons ago, will remember that Tx and RX antennas were
pretty long and only represented 1/2 the WL (I think it was
1/2)<BR> <BR>Dean Pappas, Ed Alt and Jim Oddino can explain further if
needed<BR> <BR>BTW, tuning a pipe on a 2 stroke requires similar
understanding between rpm (base frequency) and tuning length (wavelength of
the exhaust pressure front and type of exhaust) to achieve the desired
resonance....similar to electrical antennas.
