Also, is this for pirate radio? Chris |

Also, is this for pirate radio? For 'educational purposes only', you could try these two programs. One calculates the impedance at the feed-point of an inverted-L end-fed antenna, and the other calculates the values of the L and C which you need for an L-match tuner circuit. endfeed.exe l_tuner.exe (that's L-TUNER-EXE) These - and many more wonderful programs - are available from this website: http://www.zerobeat.net/G4FGQ/ http://www.zerobeat.net/G4FGQ/page3.html#S301" -- Ian |
