The W3DZZ Antenna

Posted on January 6, 2016January 7, 2016 by Simone

The W3DZZ antenna revisited. A multiband antenna 80 to 10 meters by using traps for 7 MHz

Construction: I made and put this antenna up the Friday afternoon before the ARRL RTTY Roundup (1999)! It took me about 3 hours to make and install on the tower. Most of that time seem to be used untangling the wire..hi hi I made the antenna 142 feet long. Use tiewraps at each of the…

6 Meter Halo Antenna Design

Posted on October 17, 2015October 17, 2015 by Simone

This halo antenna by KB1DIGÂ is made with a true Gamma Section this time and is fashioned from aluminum. Most of the parts are leftovers from old car projects. The best part is it’s omnidirectional! The 3/8″ fuel-line I used came from Summit Racing Equipment: http://store.summitracing.com #SUM-G2538, and a 25′ section costs…

The ZS6BKW Multiband HF Antenna

Posted on September 29, 2015April 26, 2016 by Simone

This is the antenna for you guys who want to get on HF effectively, and haven’t too much space or cash to throw around. Actually, it’s a design from ZS6BKW (aka G0GSF), similar to the G5RV, but it actually resonates on five bands, (well 6, actually) and doesn’t rely on a tuner (ATU) to make…

Step-By-Step Construction of a 4:1 Current-Type Balun

Posted on September 24, 2015September 24, 2015 by Simone

Article by Charles Greene, W1CG My 4:1 current-type balun is wound on a FT-114-43 core. The FT-140-43 is a little easier to work with, and maybe the FT-140-77 would cover 160-10. This one is reasonably flat from 4.5 to 35 MHz but drops off a little at 3.5, 40-ohms with a 200 ohm resistor on…
