What is a 160 m antenna?
What is a 160 m antenna?
My first 160 m antenna is a modification of a 20 meter collinear vertical that I was experimenting with. A diagram is shown in the figure on the right. For the 20 meter collinear, there is an upper half-wave section, a phasing inductor, and the lower half-wave section that includes the feed point from the 75 ohm coax.
What is the best way to feed a 160 m antenna?
Applying this lesson to the 160 m antenna suggests the inverted L has the potential to work better, with a top horizontal section that will act somewhat as a capacitive “hat”, and some shorter elevated radials also acting capacitively. My approach for feeding a vertical wire antennas is to use 75Ω coax feed line directly to the main vertical wire.
Is there a way to add 160m to an 80m vertical?
But most of them don’t start out with a 80m vertical and then adding 160m onto it as a retrofit. The first version of the vertical found me adding a trap and some cap hat wires to provide 160m operation. It was functional and a good performer. And this season, I wanted to fix the big problems discovered since it was put up 9 months ago.
How good is the performance of the 80m antenna?
The performance on 80m wll be excellent. On 160m the performance is also very good. NOTE: I HAVE NOT PERSONALLY TRIED THIS ANTENNA YET, but Cornelius has built and used it several years ago. The deminsions are approximate values, as the actual dimensions will vary slightly from one installation to the next.
