All Band Verticle

The initial plans for this antenna are from https://www.dj0ip.de/; It looked interesting (and easy to build)

Please note this antenna requires

• No verticles
• A symmetrical Matchbox (Prefered)
  • Or a current Balun

MMANA Model

This for 20m - but with a decent matchbox tuner it should work (according to the web site owber from 80m-10m, interestingly L.B. Cebik, W4RNL (SK) noted this as a 30m-10m antenna).

I have raised the base 1m - so you will need a 13m mast.

Radiation pattern on 20m is excellent. Omni gain - and very very low radiation pattern.

15M is still good - although slightly less optimal than 20m

10M is very nice pattern also.

## 4Nec2

The 20M expected radiation pattern is the same as MMANA (hurray)

NEC File

This is the definition for 14.150Mhz. Note. I have set the expected impedance as 450 Ohms in 4Nec2.
