End Fed Long Wire for 160-6m Operations

I forgot to mention, I am using a 9:1 UNUN at the feed point followed by 90’ of coax (LMR-400) serving as the counterpoise, followed by a good common mode line choke which then feeds into the shack with another 85’ length of LMR-400.  The coaxial counterpoise is zip tied to my aluminum fence (~3’ high) for the first 75’.  I couldn’t tell you if this coax is capacitively coupling to the fence, but I bet that it is.  I also tried adding a second 70' counterpoise (using the same wire as what I used for the antenna), but it actually made things worse.

Gutter Mast

I'm kind of lazy, and I hate pulling out ladders, so I came up with an easy way to mount a small antenna from my gutters. I can install or remove the mast/antenna(s) from a second floor window.

The above shows my Meshtastic antenna. The mast attaches to the gutter with cheap hooks from Lowes (see picture below). Clothesline is tied to the bottom of the mast and is then attached to a weight on the ground with just enough tension to keep the mast upright. To install it, I open the window, reach out with the mast and hook it onto the gutter, and drop the clothesline to the ground. I then go outside, pull tension on the clothesline, and tie it off.

I have another mast on the other end of the house with a broadcast FM antenna and a GMRS antenna. I have had both masts u…
