Way back, NSA was specified at three-meter separation, using tunable dipoles. Because at the low end (30 MHz and up) the dipoles were longer than the separation between them, the NSA curve was flat, instead of rising at 20 dB per decade with increasing frequency, as it did above maybe 80 MHz or higher (if memory serves).
My question is: was there a similar type curve for ~140 cm biconicals, where one would expect the 20 dB per decade slope to be valid to a lower frequency before flattening out? Anyone recall this?
