I have constructed a 915 MHz 1/2 wave, end fed antenna that fits onto the
end of a SMA plug based on help from you guys.

How are you matching the very high feedpoint impedance?

I have some pics of the construction if anyone is interested in taking a
look.
Where is the appropriate place to post these jpg files ?

Some of us have web pages from qsl.net for that purpose.
There is also a netnews group for that purpose. I think
it is alt.binaries.

He is feeding the 1/2 wave antenna in the center, where the impedance will
be somewhere around 70 ohms. His coax feed line is located within one half
of the antenna and exits the 1/2 wave, center excited, dipole at the "high
impedance" end of the dipole.

David sent me some pictures. The antenna looks quite good.

The effectiveness of the "choke" that attempts to disconnect the dipole
from the feed line may be less than ideal, but it is yet unknown how good
this antenna needs to be.
