Omni or skewey?  Time owned: more than 12 months
Needs help - the feedline radiates like crazy due to the no ground radials. The ARX-2B antenna with additional length and ground radials make for a much cleaner pattern! a 1/4 wave ground plane will probably work better. I'm not downing Cushcraft because they make nice stuff, but the original "Ringo" design needs to be retired.

First, this is not a "Ringo Ranger" model at all, it's a "Ringo" (without the "Ranger") and is a 30 year-old design with tens of thousands in use worldwide. Considering the entire antenna is built of three pieces of aluminum and a few machine screws, it's amazing how many people install them incorrectly.

The AR-2 is a base-fed half-wave, which means it has a natural feedpoint impedance of thousands of ohms. To match that to 50 Ohm coaxial cable, an extremely critical matching transformer is part of the base assembly. This is the "ring" part of the "Ringo." The tap point on the "ring" is so critical, that if you miss the correct tap point by even 1/16", the antenna will not function. Remember, this is a matching transformer with a transformation ratio of approximately 40 to 1. There's absolutely no room for error in its adjustment.

The reason it's even an adjustable device is to allow the AR-2 to be used over a very broad range of frequencies, from about 110 MHz to 180 MHz. By lengthening or shortening the vertical radiator (which is adjustable by slipping one piece of aluminum tubing inside another and tightening a clamp), and adjusting the tap point on the ring, the AR-2 covers not only the 2m ham band but down into the aviation band (108-136 MHz) and up into the public service mobile-telecommunications band (152 to 174 MHz). A very versatile design, indeed. However, any time the operating frequency is changed by more than 1 or 2 MHz, the ring tap point requires adjustment.

When properly adjusted (check with VSWR bridge, Antenna Analyzer, or other popular and readily available instrumentation) for both length and ring tap point, the AR-2 provides about 0.0 dBd gain over a vertical dipole, which is exactly what it's supposed to do. Exactly. It can do no more, and no less, than this. There's no place for it to lose signal, lose power, dissipate energy, or have any loss. It is all aluminum, and when properly adjusted, 100% of all signal supplied to it will be radiated; same goes for receiving.

A piece of coax would work better!  Time owned: 0 to 3 months
This has to be one of the worst 2 meter antennas I have every had the displeasure to fool around with. I already had an MFJ 6m/2m dual band antenna on the roof and was given this antenna for free (I sure wouldn't want to pay for it!). I compared the two and on average, I saw a decrease of 2 "S-units" between the MFJ and the Ringo, with the MFJ winning!

Please realize, this is the AR-2, not the ARX-2. They are different antennas. See the reviews on the ARX-2 before deciding if you want to pick one of these up.

Nice little antenna  Time owned: 0 to 3 months
This little antenna is a gem, easy to setup, inexpensive and rugged. At a mere 15 feet with a radio pushing 50 watts, I was hitting repeaters full scale 60-80 miles away at basically sea level elevations. This antenna sells for $39.95 to $47.95 and is a good bargain.
