The new antenna has made a substantial difference in the performance of this repeater.

If you had trouble getting in before, try it now and you might make it.

Many thanks to my brother, Jeremy, for giving us yet another of his early Sunday mornings.

Still to come…

100W Amplifier and Bridgecom Duplexer.

 

NOTE!

If you can hear the D-Star repeater, but cant get in, use VFO mode to tune 444.675 and set your mode to DV.

Most users with an issue have programed a digital memory, which we are not ready for yet. (The D-Star Gateway System is coming soon.)

Please congratulate KT4TAC Tom Coudriet to the role of Vice President of the Charlotte Amateur Radio Club for 2024.

The club would like to thank Mike Wentz KE4EHC for his service and on going contributions to the club.

Congratulations to Ted (KE6QEY) for retaining the office of Club President for the 2024 term.

Tom (KT4TAC) was elected as Vice President, while Gale and Buck committed to another year of service in their current positions of Secretary and Treasurer.

I am always thinking of antenna projects. Here is one I came up with to entertain myself over Thanksgiving break.

Many people who have a 1.2ghz radio do not have an antenna for it.

This is a simple 1/4 wave antenna that can be built in about 15 minutes for the 1.2ghz band.

Material list is as follows…

  1. Mason Jar Lid Like this.
  2. N-Connecter to PL-259 connector adapter. Like this.
  3. Almost 3″ of bare #6 Like this.
  4. The coupling ring from a broken PL-259.

 

Construction is as simple as drilling a hole thru the lid, snipping off a measured length of wire, and assembling the parts as pictured.

 

The antenna should be installed with the least amount of feed line possible, due to the tremendous loss it presents at these frequencies.

If you have a VNA, the antenna can be fine tuned by moving the copper wire up and down by tiny increments.

If you do not have a VNA, just use the SWR meter on the radio, as the antenna should be very close to perfect at the length pictured.

Also, screwing a mason jar over the top would make for a good outdoor antenna, however, feedline length is such an issue that having the antenna in the shack is usually the best bet.

Cheers!

 

PS

This technique works on 70cm with a cookie tin or 2m with a pizza pan.

I also use a barrel connector instead of the N-adapter for 2m.
