Wow, interesting comments to be sure. Let's correct some obvious errors......

The I-10K can be ordered with the UHF or N-Connector. The I-25K only comes with the 7/16 DIN connector. The N-Connector is not rated for 25K. Other than the connector change, there is NO DIFFERENCE between the I-10K and the I-25K. But I already correctly stated this. The insulator disc is also unique to the I-25K and does not add any mechanical or electrical advantage to the antenna. I wasn't wrong the first time I said it and I'm not wrong this time either.

I won't include the whole message in order to save space, but the engineer's statements are foolish. The whole purpose of the loops on the Avanti Sigma 5/8, the Maco V58, and the I-10K is to get this part of the antenna out of the plane of the vertical radiating element, thus eliminating any affects of the loops/trombone. The Sigma 5/8 and the I-10K also use an elevated main radiator which has been PROVEN to have less loss than the design used by the Maco/Wilson and the HyGain Penetrator. Its true the Maco V58 is a good antenna, but it does not perform better than the I-10K. Not now, not ever.

The Top One is a copy of the Avanti Astro Plane antenna. It is argued that the design of the Astro Plane puts all of it energy in a 12' section allowing it to be mounted higher without breaking the 60' rule. Your standard ground plane radiates from the bottom which can be as low as 40' down from the maximum legal height. The Astro Plane is upwards of 48' while still being legal. Its an interesting concept and those antennas have worked very well for a long long time.
