On what? The "ducky" antenna?
The short rubber antennas on hand-held radios (a.k.a. handie-talkies, or "HTs") are very often colloquially referred to as a "rubber duck" or just "duck"... Perhaps something to do with it being made of rubber material and the fact they don't work as well as full-length antennas do (a station with a weak signal is sometimes called a "mud duck" because their signal is "down in the mud", or static. So "mud duck", rubber, and... well hopefully you get the point lol). Maybe someone else here can provide some different versions of how it came to be called a "rubber duck"
The Baofeng UV5R dates back to somewhere around 2011 I think, and had some terrible reviews when it first hit the market, much of it centered on it's noisy receiver which nowadays most people just accept with the territory in cheap Chinese radios (CCRs). It sold for around $45 at that time too. The GT-3 Mark-II I think debuted in 2014. It's a little more modern design and includes a better "rubber duck" antenna in the package than the UV5R (a little more slender & floppy, but with much better RX & TX performance, on par with antennas included with the likes of radios from Yaesu, Icom, etc.). It's a slight hair over 8" long from base to the tip (not including the threaded connector). I don't have a UV5R on hand to measure at the moment, but I think it's provided antenna was around 5-6" tall if my memory is serving correct.
"Chirp" is free radio programming software that works very well to program these things. Chirp has preloaded lists for the MURS, GMRS, and FRS radio services all you would need to do is select them and then download or copy & paste them onto the radio. This is important too because you don't want to have accidentally programmed transmitting frequencies in the radio that could potentially interfere with another radio service such as police or fire.
A good website to check out is
