Antenna Improvements

Over the past couple weeks I made some antenna improvements.

For 160m, I added a remote vacuum relay to switch a hairpin matching coil in-and-out. I use the coil to match the antenna on 160, and switch it out on 80 where I don’t need it (it actually worsens the match on 80).

I also put up a new vertical, for 40/20/15m. Again, I used parallel radiators to share a single radial field. The antenna sits over 40 radials, and works well for the 2nd radio on these bands (SO2R).
