[Antennas] B&W AC 1.8-30 vs BWD terminated antennas?

[Chris Boone]

Yep, I did mistaking state that without thinking about the Rhombics,
etc..
such long wire multiwavelength antennas like the ones you mention do not
have a 100watt resistor at the end like the B&Ws do and thus do not
dissipate power...but radiate their RF power long before the signal gets
to the resistor. What is left is absorbed by the resistor to reduce
SWRs...but the antenna is such a length that is radiates and does it
well..
The B&W below 10 Mhz is SHORT wavelength wise and thus do not radiate
before the resistor absorbs the RF.
