Nice shiney aluminum standing tall, and that’s it. No big ugly radials anywhere from head to toe. At first glance, it is pleasing to the eye.

The design of this antenna is so simple it is almost stupid. I am just so impressed by the performance of the CHA250B, that I thought it was worth a page on my website. So take every word I say here as pure and quite honest. Just to reassure you, I do not work for NCG Company, (the parent company of Comet antennas), and they do not pay me for this review. (Except the JTV680 which just uses a big fat resistor to rob your power.) Then there is my favorite. That means they all have a poor impeadence match which robs even MORE of your power. The coil is basically a fat 50 ohm resistor type that sucks power away.Īnd every one of those antennas have high SWR throughout the HF band that requires you to have or purchase an antenna tuner. The JTV680 is made of thinner lower grade aluminum that will break easier in the wind, and “JETSTREAM” makes a real look-a-like, copycat version of the CHA250B called the JTV680. “HY-GAIN” has the AV-18AVQII, but again with all of those power thieving traps for certainīands, and a separate add-on load coil for 80 meters. Not a bad antenna, but it is loaded with several power robbing And this thing has way too many ugly radials sticking out in allĭirections that can break off in the wind. But in reality, it is a center fed vertical dipole. It has a cheap design with a separateĪdd-on load coil with a flimsy wire that connects the coil to the main element. “DIAMOND” has one similar to the Comet called the BB7V. “BUTTERNUT” makes the HF6VX, but you need to buy extra kits to add some of the bands. There are a few compromise HF vertical antennas within the same class as the Comet CHA250B on the market. I saved for further reference, author is K3DAV whose site is gone qrt.

While evaluating HF multiband vertical antenna I found this interesting review about the CHA250B by Comet.
