First of all, thank you very much for the add to the group. I've only been a licensed ham for a bit over a year and am just getting into HF. I wanted to start out with a hands-on experience I could handle, but I've run into a small snag. I put up an 80m skywire loop, which is about 25-35 feet off the ground, fed with homebrew ladder line. All wire is 12g stranded copper with plastic sheathing on the wire. I used electric fence insulators to make the spacers, about 3 1/2" spacing and the total length of the feed line is about 36 or 40 feet (I'll get a better measurement).
While the reception appears fine, when I attempt to transmit, it appears there is no propagation, just RF in the house: so much so that it takes the wireless Internet modem offline temporarily. That's why I'm guessing RFI. I've sought the advice of a couple other local hams: one said swap the open wire for coax and the other said lengthen the feedline to about 60 feet.
Does anyone in the group have experience with this issue, and if so, what did you do to rectify it? I'm using an MFJ 969 roller inductor tuner with its internal 4:1 balun. Left to my own devices, I'd lengthen the feed line first and if that didn't do the trick, I'd look at coax.
Thanks for any advice you may have to offer,
