Balcony antenna extension
I used to use an old CB 27 MHz half-wave antenna which had a broken matching coil. this I used as a 1/4 wave antenna for 14 MHz, after removing the matching coil
Butternut HF2V for the 160-30 meter bands
During these three years, the antenna has been standing and performing very well without any need for fixing or tuning it. I have done a visual inspection and tightened the guy ropes every now and then, but that's all
Cushcraft R5 1/2 Vertical
The 17ft half wave vertical is covering the 10, 12, 15, 17, and 20m amateur bands. The antenna does not require traditional ground radials
Design of a 20 Meter Top Loaded Vertical
A top loaded vertical antenna has several advantages over the conventional vertical, but the biggest advantage is that it's shorter in length
