If a yagi reflector, reflects nothing, what would account for the forward
gain of only a driven element and a "non-reflector?"
I am not asking to be a smartass, but looking for some evidence of the
ethers properties... (some might say I am looking for aliens? grin)
Warmest regards,
John

| Exactly Gene.
| This is why the thread asked for a "definition" first for director and
| reflector.
| As you are probably aware a yagi reflector does not reflect anything.
| Some would say that a dish "reflects but not a element.
| I am still a bit gun shy after the last episode where TOA was not
| defined in the IEEE dictionary thus many feined knowledge on the subject.
| I suspect tho that the nomenclature started with the Yagi and then
| spread to other array design descriptions.
| If however a Yagi reflector does actually "reflect" then your scolding
| is correctly directed at me.Perhaps we should first look in a dictionary
| for the word "reflector"

| Art,

| Think again about what you wrote.

| "I have oft times changed a single element into two closely coupled
| elements and where one is short and one is long relative to a driven
| element."
|
| Why would you mis-attribute your application of standard terminology to
a
| new experimental situation as a "poor translation"?
|
| The appropriate terminology for the various elements is generally pretty
| clear from the physical design and performance of a Yagi antenna. When
| your experiments go beyond the original design you are on your own.
