This is the old city context, were the Stealth Zepp lives! Many houses in a relatively small area. That means Stealthy antennas, QRP power and smart modes such as CW, Pactor and PSK31.

Situation overview. This is the Stealth Zepp's enviroment. Can you find it? An old city, with new houses and appartments. Note the support lightpole in the yellow circle.

Please note that one end of the open feedline ends in....nowhere! Thin air!
The other end drives the end of the dipole. Both sides of the open line see a very high impedance!

Meet the Stealthy Zepp! Do you see the white church tower in the background? That is where photo #1 was shot!

Feedpoint. Excessive use of Telco Tape :)

Current and voltage feed on calculated band and harmonics!

Feedline roof entry

Support pole with monofilament fishing line. Is this puppy stealthy, or what?
At the left side of this picture you can see the end-isolator.

Stealth Amateur Radio. A very good book on Stealth Antennas! Highly recommended!

Stealth Amateur Radio backside of the book!

Rothammels Antennenbuch. In my opinion the best source on the topic of Antennas! Get your copy! Ofcourse, you need to read German language! :)
