- Paul N0AH, is having "fun" tuning his MA160V vertical antenna: <snip> Now, do I just use the Pro's III tuner or the Amidon UnUn to minimize SWR at the feedpoint <snip> Paul, You could also try 10 or

- <SNIP> You could also try 10 or 12 turns of #12 or 14 gauge wire, 2" diam across the feed point and ground. Spread/compress the turns to get the lowest SWR/best match. Just to be specific: this "hair

- If it improves your match, you also gain the advantage of having the vertical grounded..thus giving you less static and noise to contend with on receive. Good luck, es vy 73 John EI7BA ______________

- Not going with hairpin match- The UnUn has been awesome- Measured at the feed-point, my resonant point is at 1.818Mhz and the SWR 1:5:1 now using it to match the antenna and coax line-- Using 50 feet

- The antenna driven element also has to be capacitive. The ideal Z for a hairpin match is 25 - j25. A good tutorial is given starting on page 26-11 of the 20th edition of the ARRL Antenna Handbook. Ha
