[ogWiFi] Looking for Directional Antenna

[Scobie, David]

Gentlemen, I have a DC to 7GHz spectrum analyzer and access to a vector
network analyzer if we want to do some characterization of antennas at
some point.  

I am thinking of buying myself a VNA but I haven't quite decided on the
kind yet; so our friend Dr David Conn is willing to do some work with
me, especially if it leads to another post retirement publication....

David

Well, ogWifi is just borrowing it to see if it solves a customers
problem. He wants to fire out into a park, but its through heavy
foliage. It is a converted satellite parabolic dish antenna. I am very
interested in seeing what the conversion looks like and see its
performance. I picked up a discarded dish with mount in beautiful
condition from somebody's garbage about 2 weeks ago with the thoughts
of converting it to wifi.

I saw the plans for a helix online. It looks pretty straightforward
except for the impedance matching vane. That seemed like black magic
to me. Do you have instruments for testing it once your are done, like
a VSWR meter?
