Having researched options for extending the range of WiFi receivers and broadcasters I ran across lots of designs for home made antennas, some with ranges of many miles. My curiosity piqued I decided to build a very long range “double bi-quad” antenna.
I needed a piece of scrap 12 or 14 gauge household wiring, a short piece of half inch copper pipe, a piece of sheet copper about 5″ x 9″, and some low loss coaxial cable. So off I went scrounging.
I was able to get the scrap wire and copper pipe with no problems from a scrap dealer up the street not to far and ordered 15 meters of the right type of coaxial cable and necessary connectors from a vendor on Mercado Libre, Latin America’s eBay affiliated online market place. Finding a piece of copper sheet, however, has been difficult.
I have checked in every hardware, electrical supply, and kitchen equipment store in Centro and in the area of the Mercado Los Sauces with no luck in finding copper sheet. A couple of days ago, though, I asked in a local plumbing supply store and the nice proprietors directed me to a metal dealer just off Avenida Lazaro Cardenas, a good ways North from my apartment.
So yesterday morning off I went to locate the metal dealer. Being Sunday I knew it would probably not be open for business, but I need the exercise and it was a beautiful sunny morning for an urban trek, up and down through the hills of Xalapa.
My map of the city doesn’t include a scale so I don’t know for sure how far I walked before locating the metal dealer in a very nice Colonia Rafael Lucio part of town, but I had been walking for an hour and a half. It was another hour and half to return. I plan to go again this morning.
The real treat of my long walk was encountering the Plaza Xalapenos Ilustres, a tree lined pedestrian plaza which separates the to and from lanes of Avenida Xalapa and which stretches from block upon block from the Avenida Presidente (Lazaro Cardenas) to Avendia Americas. The stretch of Avenida Xalapa passes the Pantheon Xalapeno (a large cemetery), a large sports school, and the famous Museo Antropologia.
The plaza, according to an informational sign, contains 1733 trees, predominately Sweetgums, Mexican Sycamores and Shamel Ash.
