I had some time yesterday afternoon to tune up the wire i am using with the 1:1 Balun dipole project. I set myself up outside and ran out the dipole as I would deploy it for a SOTA activation. The antenna was too long as expected given how I had cut the wire! I started…
To Balun or Not to Balun, this is the question? Like Ford vs Holden, Canon vs Nikon or Yaesu vs Icom; the world is divided into two camps on how best to connect a resonate wire antenna to a bit of coax. Until now, my dipole had been direct connected. and this had worked as…
