Here's my plan:

- String up about 30' of copper wire in my suburban backyard using
insulators and rope.

- Solder a feedline to one end of the antenna wire. The feedline will
be made of ordinary insulated wire, not coax.

- Solder a banana plug to the end of the feedline.

- Bring the feedline into the house through a window.

- Attach the feedline to the antenna input (SO-239) of a MFJ-1020c
active antenna/preselector.

- attach the MFJ-1020c to my Sony 7600GR using some sort of pl-259 to
mini (1/8") patch cable. Universal Radio has a PL-259 to mini adapter
(#1619). Alternatively, Durham Radio has this cable, which I'm
assuming will work for my purposes:

Are there any problems with this setup, other than the lack of
shielding for the feedline?

For example, is there a problem with using a banana plug to connect
the antenna to the MFJ-1020c?

Also, any thoughts on grounding? I think there is a difference
between lightning grounding and RF noise grounding, but I can never
figure this out.

Thanks.
