PRO401HH

Works great

I had a Cobra before but it had a lot of issues. When I got this one I put it in my car and plugged it in and it's working great. Although it doesn't hold the channel when I turn it off and turn it on It's a pretty good radio.

Unfortunately it took me too long to figure out this unit was not working on batteries. I assumed there was no radio traffic. But it turns out, it only works with the AC adapter plugged in. Which makes it useless for me. A loss. I would recommend not purchasing this item.

I've been using this handheld CB radio for about 5 years now. It works well for me, but I had to upgrade the antenna. Something that most people need to understand is that the "rubber duck" antennas that are supplied with these CB radios, while being durable, are very limited in range. Your more classic CB radios that were made in the 70's and 80's would come with a telescopic 4 foot antenna. CB radio requires a long antenna. The CB radio itself does what it can, but you have to help it along with purchasing a better antenna. It's unfortunate, but if you want to get anything better than 1/2 - 1 mile in range, than you'll need to upgrade your antenna. You can get decent ones that will bump you up a few miles more from $17 to $40. Go on YouTube and watch some antenna reviews. There are many who have done the work of reviewing them by practical application, meaning they go out and test different antennas at different ranges, and you get the benefit of those reviews. Regardless of manufacturer these days, all modern handheld radios need antenna upgrades.

kind of has a short range but does pick up close trucks definitely worth having

These has longer reach than the average walkie-talkies, but not long enough to cover a mile for realistic application.

This radio seems very well built and designed like all the Uniden products I’ve owned. The sound quality is great, and it takes about 10 seconds to figure out how to use it, it’s very simple. I will say it drains batteries fast, so get the rechargeable batteries for it. Seems to have decent power and range with the right antenna. And the ability to charge the rechargeables with the power cable is neat. Also a great value for the price, can easily be made into a small mobile unit for a car in temporary setups.

After doing my research on handheld cb radios I came across this Uniden pro 204hh model and for my portable use this radio fits the best! I watched several YouTube videos about users bench tested this radio and it's outperformed the factory specifications on power output and with the 51" upgrade telescoping antenna perfectly performing therefore I'm very happy with my purchase and highly recommend this h.h. cb radio to everyone and for $59 dollars this is a good price, worth every penny in an emergency! Thank you Uniden and Amazon, great product.

Absolutely love this thing. It reaches 8 miles, at least. Bought it because my company owned, factory installed, company maintained one doesn't work properly and I need a cb working in the mines and this hand held is perfect.

Pues el producto es bueno, funciona, solo que el alcance es muy corto, co.prare una antena extra

Great purchase. Price is good. Only had it for a weeks and have picked up a few CB users in my area.

The radio has a BNC connector, so the supplied short "rubber duck" antenna can easily be replaced by a longer antenna that extends the line-of-sight range. Since you are probably buying this to use from a vehicle, you will be disappointed with the range if you try to use the stock antenna inside a vehicle. You should also buy an antenna that you can mount outside the vehicle. Longer/taller will be better. Note that most external antennas have a cable with a "UHF" connector for a non-handheld CB radio. That can be used, but you will also need a BNC to UHF adapter (not very expensive). This radio is advertised as "4 Watts." The FCC limit for conventional amplitude modulation (what this and most CBs do) is a 4 Watt carrier. When 100% modulated, that gives a 6 Watt total power level. (For single-side-band [SSB], which this radio, and most CB radios do NOT do, the FCC limit is 12 Watts). I bought a cheap power/SWR meter ( https://www.amazon.ca/dp/B086QPTXQT?psc=1&ref=ppx_yo2ov_dt_b_product_details ) and verified that it was within the 10% power accuracy spec by comparing it to an oscilloscope when driving a 50 Ohm terminator (yes, I'm a nerd). If I use 9 Ni-MH batteries, the carrier power (no voice into the microphone), is only a bit more than 2 Watts. The spec sheet says 4 Watts at 13.8 Volts. But the supply voltage at 1.2 volts times 9 Ni-MH cells is only 10.8 Volts. If you use 9 alkaline batteries at 1.5 Volts per cell, that's 13.5 Volts. A car battery is about 12.6 Volts, and when the engine is running, the alternator will run at around 14 Volts to charge the car battery. The radio has an external-power jack, and comes with a cigarette-lighter plug. It will use the cigarette-lighter power instead of internal battery power when plugged in, and re-charge Ni-MH batteries (if the switch in the battery compartment is set properly). I have a 15 Volt power supply that fits the cigarette-lighter plug. Using that power supply, the carrier goes up to about 4 Watts into a 50 Ohm load, vs about 2 Watts on Ni-MH batteries. So I conclude that the power is pretty close to as-advertised, and at the FCC limit, if you use alkaline batteries, or the cigarette-lighter plug, but lower with Ni-MH baterries. You will probably be happier for use in a vehicle if you use the cigarette-lighter plug to get a bit more power, and use the tallest external antenna compatible with conditions.
