80-10 End-Fed Half Wave Antenna III

 I tightend up the slack that I had in my 80-10 Meter Lucky 7 Antenna. Here are the new SWR measurements:

Band Frequency SWR
80 3.573 MHz 2.0
40 4.074 MHz 2.0
30 10.136 MHz 3.0
20 14.074 MHz 1.4
17 18.100 MHz 3.0
15 21.074 MHz 1.4
12 24.915 MHz 2.0
10 28.074 MHz 5.8

The SWR measurements made a big increase but not quite where I want them. So I will just need to keep moving on. 

If you have any comments please leave them in the comments below. Or you could just email me at Aaron@K5ATG.com

Until mext time stay radio active.

80-10 End-Fed Half Wave Antenna II

 

Strung up my 80-10 End-Fed Half Wave Antenna. The feed point is a 20 foot tall flagpole right outside my bedroom window. Then it travels west to another mast. From there it goes to the North West cornet of the house. After that it goes South East to the shed. It is 135 feet long, here are the first set of SWR measurements:

Band Frequency SWR
80 3.573 MHz 3.0
40 4.074 MHz 2.6
30 10.136 MHz 5.8
20 14.074 MHz 5.8
17 18.100 MHz 1.9
15 21.074 MHz 1.3
12 24.915 MHz 2.6
10 28.074 MHz 5.8

I tried to set it for all of the FT8 frequencies cause that is where I spend most of my time.

Here is a Google Maps vire of my antenna


I'm calling this the Lucky 7 Antenna. As you can see I got that from that layout

That is all for now. If you have any comments please put them in the comment section below.
