Stealth antenna? Explain this one.

[pro151]

Never heard of that one, looked it up right quick and I am not too sure about the built in Balun. I am sure one of the more knowledgeable antenna guys will pitch in with a better answer than this.

The Comet CHA250B broadband vertical antenna will amazingly cover 75/80 meters through 6 meters with no gaps! Transmit range is 3.5-57 MHz and receive range is 2-90 MHz. SWR <1.5:1. This 23.5 foot vertical requires no radials and weighs only 7.1 lbs. The antenna consists of five sections of aluminum tubing that slide into each other. The bottom section has the matching network built-in. Only two simple measurements are required during the easy assembly. It can handle 250 watts SSB and 125 watts FM. SO-239 input. Mounts on a 1 to 2 inch mast (not supplied). Rated for 67 MPH wind survival.

Here is a great article where VK5VD takes one apart to show you what is in side the matching network at the bottom.

I Installed this antenna about 30 feet off of the ground. Observed 1.5 or less swrs from 14-28 MHZ. Heard some hams on 20, 17, and 10 meters. Could not work any of them. Comparing this to an IMAX 2000 at about the same height. I can load the IMAX from 17-10 meters. Talked to 4 hams and noticed from 1 gentleman 7-9 s units. Switched to the Comet and he went down to 0-1 S unit. That is just not acceptable to me. Returned to store. Either this antenna was a lemon or just does not work at all. Stay away from! I am in the process of getting my money back and will update this review. I did check and double check all connections. That did not help. Rig used was an Icom 746 non Pro. Thank you.

Just because something has Low SWR........
