If you don't like my opinions, thats too bad. An antenna is an antenna is an antenna. Do you think when I switch from a SWL to a ham band, I need to switch antenna types? LOL...You guys kill me.. MK Well how can your receiver work with an antenna made for transmit 8-} Basically (theoretically) an antenna made for transmit is just as suitable for receive. This is called reciprocity. This concept falls apart two ways in practicality: 1. The transmit situation has to handle power the receive situation does not so for transmit the antenna elements need to be "beefier." 2. A less than full size antenna made resonant may work very well for transmit but for receive not as well. Less than full size for receive lowers the antenna efficiency. Telamon, Thanks for the friendly answer - however, I was aware of what you mention. My earlier response was just a case of me being flippant in my response to MK. When I post whether a new thread or in this case a reply I try to be informative as this is not like email where a reply would go directly to you. Hopefully other people reading the thread get a better idea of what will work better for them. Besides there is no way for me to know what you know or what experience you have except for what you explicitly write and I have to guess the rest. A level of knowledge a person has is an interesting thing in itself. Some people are aware of the reciprocity concept and leave it at that but you can always look at things in a deeper way that modify or even appear to reverse a rule. -- Telamon Ventura, California |
