1/4 wave antenna’s. Approx 1 m. The 72Mhz wavelength is
416cm for a full wave (varying some for which specific frequency you
were on.<BR><BR>The 2.4Ghz wavelength is only 12.4cm or about 4.8in.
So an equivalent quarter wave antenna will only be about
1.2in in length.<BR><BR>-M<BR><BR>PS for those that care, wavelength
(in cm) = speed of light (in cm) / Frequency (in cycles per
second)<BR><BR><BR>On 5/8/08 10:54 AM, "rcmaster199@aol.com"

style="FONT-SIZE: 11pt"><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.
