[NSRCA-discussion] 2,4 Module

***When you realize all this from that measley little 4" antenna, it's almost jaw-dropping.??***

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)

Dean Pappas, Ed Alt and Jim Oddino can explain further if needed

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. QED
