J-POLE ANTENNA BUILDING ACTIVITY AS SUCCESS!

If you missed the J-Pole building activity held on January 15th during the monthly Emergency Communications Response Team (ECRT) meeting, you missed a great activity!  Twenty-two area hams came together at the Federal Way Church of Christ's teen center & had a great time putting together easy to build roll-up J-Pole antennas.  The simple list of materials includes RG-58 type coax cable, some 300 ohm twin lead, a BNC connector, and some solder.  The J-Pole antenna provides higher gain than a "rubber duck" type antenna which comes with a handheld radio.

Many thanks to Jerry-KC7NA for
organizing this fun activity!

Kris-KE7LCX & Rich KC7DZD read through the directions for before starting their build.

Measuring the RG-58 coaxial cable. Is it measure once, and cut twice, or the other way around?

Nick-NI7CK and Jerry-KC7NA making sure their coax is long enough.

Dick-KD5HXE is prepping his coax cable for soldering.

Trimmng the coax. Look out for sharp objects.

Heating things up.

Prepping more cable.

Dave-KC7RRH making the connection between the RG-58 coax to the 300 ohm feedline used for the radiating element of the J-Pole antenna.

A little dab (of solder) will do ya.

Doug-KE7YWO making things look easy.

Apply a little heat, and a dab of solder.

A completed solder connection.

Testing of the new antenna. VSWR looks a bit high, but the freq is a bit low.

Weatherproofing the completed foldable J-Pole antenna.

Look at all of those folks! Thanks Jerry-KC7NA for organizing this activity.
