I have an Antron 99 up Ive used them for years but I also have an IMAX 2000 and was wondering if there is a huge difference between these and is it noticanle enough to be worth pulling the ANTRON 99 down and putting up the IMAX 2000?? I use my A99 for 10 meteers aswell as 27 mgz it also tunes into 12 meters nicely. I read a few articles on EHAM about some guys adjusting the tunning rings on the IMAX 2000 to work it in 15 meters and they also say theres showed a 2- S unit difference from the A99. Has any of you seen a difference between the A99 and I2000? Is it worth doing I have other antennas up but between these 2 I wanted to get a little input and or advice from people who have experienced differences or experimented with this theory between these 2 antennas.
