- *There were 3 antennas in use.

The Basic Antennahttp://www.electronics-tutorials.com/antennas/antenna-basics.htm

Overview of Antennashttp://www.ess.washington.edu/Space/ESS205/antennalecture.pdf

-*One very clearly was a Yagi.http://www.jpo.go.jp/seido_e/rekishi...i/Yagi_Antenna

- One of the others very clearly was a "vertical"

The Vertical over a Ground -aka- Marconi Antennahttp://www.midnightscience..com/_xtal/00000210.htmhttp://www.electronics-tutorials.com/antennas/antenna-basics.htmhttp://www.hnsa.org/doc/radio/chap20.htm

- and the other one was like a wire running the
- length of the parking lot and was up about as
- high as the building - then it had a middle wire
- running in to the shack with the radio. *I was
- told that was a horizontal antenna.

Dipole Antenna, developed by Heinrich Rudolph Hertzhttp://www.hfradio.ca/images/AntennaRadiate.jpghttp://en.wikipedia.org/wiki/Dipole_Antennahttp://en..wikipedia.org/wiki/Hertz_antennahttp://en.wikipedia.org/wiki/Hertz_antenna#Electromagnetic_research

Half-Wave Dipole Antennahttp://www.electronics-tutorials.com/antennas/antenna-basics.htmhttp://www.electronics-radio.com/articles/radio/antennas/dipole/half-...

-*Isn't there more specific names for vertical and
- horizontal antennas than just vertical and horizontal??

- Thanks.
