OK then what is a 'matchbox' in :

Consider the 'matchbox' to be one element

Feed-Line + 'matchbox' + Antenna Element

Yeah - Once it is 'placed' in the "System" the MatchBox
becomes part of the "System" and becomes one of the
loses within the "System"

- However:
- *a matchbox will allow you to use a poorly designed/

Now -if- That is True : Then Why Us The MatchBox
within an RF Energy Radiating System ?

- *a matchbox will allow you to "match" differing

So you are say that a MatchBox will not improve
the ERP of an RF Energy Radiating System ?
And that the Receiving Station will not hear you
'better' when the MatchBox is properly used with
the RF Energy Radiating System ?

- *a matchbox CAN allow you to alter the electrical

- are two different animals.

Electrical Characteristics = 'apparent electrical length'

A proper education in 'any' field is not a trivial thing.
And that education can take many forms : formal
practical, vocational {life time of work} and avocation
{life time hobby}

being an old timer myself - i still find simply listening
to the radio to be enjoyable ~ RHF
