hf transceiver
Dear wing
thanks for your prompt response.
is it then a correct statement that since the HF antenna is a fixed antenna and thus works for a specific ferquency, in order to match it to a difference frequency other than its natural one - 300/Mhz frequency equals wavelength -, a coupler is used to vary the length of the antenna by utilizing the airframe as an integral part of the antenna itself?
what is in plain english a wafers of dielectric?
when you key the mike and you hear the tone, that is the coupler that is matching the size of the antenna to optimize the efficacy of the system to the selected frequency, based on its wavelength?
many thanks
