Note that Bill's model shows a simple (full size) 40M Dipole at 1/2 WL (70 ft high) is 2.3 dB stronger than a 4 Square, providing further support to the notion that a 40M rotary dipole is a good, sim

In my experience models tend to fall in line more on 40 meters and up with real-world results, while on 160 results vary the most. Using a model to predict fractions of a dB, or even a couple dB, wh
I believe that most models - certainly prop models like VOACAP -- specify that they are not accurate below 2 MHz. I suspect the same is true for NEC-2 and 4. Does anyone know for sure? 73, Pete N4ZR

SNIP To my mind, the BEST solution for 40M is to pick the BEST antenna possible for TRANSMIT and use separate receiving antennas if noise (atmospheric or local) is a serious concern. For city lot dwe
