--Included: NEC2C Antenna Modeling Engine; SimNec Feedline & ATU Modeling All in one program!  

--Place an order (Absolutely Free), Gary-K7EMF will email you entire setup files for an inverted V antenna, Loop antenna(both side & corner excitation) and Vertical Antenna plus instructions for modeling your antenna, feedline &  ATU!

--After installing your antenna setup file, all you need to do is enter your antenna length, height & feedline length and you can start tuning the ATU as if you were on the air!!  SimNec    will tell you what your ATU parameters are.  If the parameters are within range of your ATU, you are "good to go".  If outside the parameters of your ATU, you may modify antenna length and feedline length to bring your ATU parameters within range!  No more "Cut and Try"!

Note: SimNec 1.5 and later uses feet in lieu of meters for the antenna parameters!

This is what SimNec looks like (Inverted V Antenna, 600 Ohm Ladder Line and Balanced ATU:
