Base Loaded 160m Half-sloper antenna

I wanted to have a resonant antenna on 160M so this is what I came up with.

Materials

Construction is pretty straight forward

Drill end caps for 3/8-24 hardware
Ring connector on end of wire that was fed through PVC tube for cap.
wrap wire around coil form. Every so often place a tap (spade connector). Closely wind wire and wide space taps for big jumps in inductance. Closely tap wire and increase space on winding for small jumps in inductance.
finish off wire with ring connector and assemble last end connector.
Drill very small “breather” hole in one end cap
Put female connectors on a length of wire that will be your jumper.

Notes

I used this on the mobile with a small mast and 56in whip for 80m.
Sometimes when I’m really motivated I will solder all taps
coil is wrapped in tape to keep it from shifting.
spacing between wire affects amount of inductance
spring on end cap was used to provide some give for wire
1:1 VSWR at 1.9Mhz. 9:1 at both ends of the band
If you can find end caps that are squared off and flat instead of rounded you will make things easier on yourself.
