After being licensed for almost 45 years now I'm thinking I'd like to try my hand at 160m at my new QTH. I'd like to start with an effective and simple to install transmitting antenna and am thinking

measure the resonant frequency with a grid dip meter and 2) measure the length, diameter, and TPI of the coil? With that I could calculate the inductance and then the resonate impedance on my own. If

Jerry, If you have a little more room, a dual inverted-L may be feasible -- which needs no traps. When you need to share a single radial system and a single high support on both bands, it is possibl

...snip... Jerry, Gary, I use such a system but with a grounded shunt fed tower and two separate shunts. However, I had to incorporate a vaccuum relay on the 160M hat wire. My two 'hats' are 180 degr
