Why is Walkie-Talkie Range Always Poor?

[@pokedude104]

I've had luck improving the reception on these by literally taping a collapsible antenna from an old broken radio I had onto the non removable one. Certainly not a substitute for a radio with a removable antenna, and it does look ridiculous, but it makes a noticeable difference

Excellent video and great advice! Don't waste money on 'toys'. If you need to have those buy one that is at least 4 watts to be useful in suburbia. In UHF communication the most important sequence in long distance contact is: 1) Location 2) Antenna ( high gain, elevation) 3) output power.

@@atomicdynamo6062 The Baofeng radios are exceptional value and don't miss very much from the more expensive "brand" name radios (Uniden, Icom etc) I've been using them for several years with no issues at all! Make sure you get the 5 watt or higher models.

[@ezralimm]

I've been messing around with a 0.5W and 5.0W tranceiver in a very heavily built up environment. The difference between 5W and 0.5W is about 800m vs 1km. It's less than you think. Note this is at 477mhz UHF CB, which probably has a bit better penetration than PMR 446. Im estimating 30-35 vs 35-40 building penetration. Gear: 0.5W AAA powered Uniden Kid's walkie talkie (UH45 w stubby antenna), vs iCom IC41s commercial 5W radio (with a ?2.1dBi Whip). Base Station: 6dBI ground independant antenna hooked up to a prosumer 5W uniden (850S).

[@RepoMan550]

Great information in this video! Only thing I will add is these radios that operate on UHF frequencies actually gets the best range inside buildings (such as schools, malls warehouses etc). With the short wave length, it more easily penetrates walls and even brick and steel structures at short distances. But UHF radios suck using outdoor in wooded areas and urban environments. Like you say, having a high antenna and being line of sight is everything for getting any kind of acceptable range.

The narrator neglects to mention that a cellphone aerial does not need to be large and that's the result of the frequency. UHF is superior to VHF in built-up areas as well.

i am very impressed what these tiny radios can do. i bought one recently for my outdoor activities such as kajaing an caveclimbing and i have to say it works brilliant. Finally no need to scream anymore to talk to my companion in an upper Level of the cave to tell him what to do... its so much easier now and we always make special rules like codes when the other one does not answer anymore or can`t hear what the radio is reseaving meaning we use the radio as a kind of Morse System. It works for us. and just for you to understand in caves ther mostle is no Satelite to reach with mobile phone and so they are pretty useless but the PMR Radios still work. Of course they are limited in Range through all the Rock and Dirt but they work and thats mostly important for us. I know i have never seen or heard of caveclimbers using those Radios to comunicate to each other but i do. Sorry if my english sometimes is a bit bad, i am not used to it.

on a good antenna you can transmit and receive from the International Space Station with just 5 watts of power. There is so much fun to be had experimenting on RF

[@stevewest6884]

The radios I bought have an ERP of 500mW. The actual transmitter is 2 watts. I pulled one radio to bits, drilled a hole in the top of the built-in ariel and slid a 160mm stiff wire down to the bottom of the helical coil in the built-in ariel, soldering it to where the connection is made to the circuit board. This gave an increase of 5db on the field strength meter (1.5 watts ERP). That 5db gain when done on both radios equated to an overall gain send+receive of 10Db. The range increased massively. 30 miles line of sight is now possible, and they work much better in built-up areas. Note, not legal, but whatever.

[@garkeinen7034]

Hi. Always try to purchase radios with removable arials like motor bike sets. There are lots of diy ext arial designs on utube with a type called a yagi (like a tv arial design) that will boost the power quite a lot....fascinating. pmr 446mhz just needs 16cm length arial to be OK. This is known as a quarter wave. A full wave is near a meter long. You can see the issue here. Go for a yagi it's not that portable but is extremely directional on tx and rx and will be amazing. Most sets that have removable arials have a connector called a SMA. A bugger to solder coax to but do - able. HAPPY RADIOIN' NO G!!!

[@Nathan1975Liggy]

Where antenna gain is concerned it is that for every 3db of gain from the antenna it is double the power out of the antenna, so 500mw into an antenna with a gain of 3db looks like 1 watt out of the antenna (you double the density of the signal level making 500mw appear to work in the same way that 1W would), however License free PMR requirement is no external or after market antenna must be used thats why most PMR 446 radios have a fixed non changeable antenna

[@donalderickson-si8ww]

that is true here in the U s a the F C C call's the shots

[@donalderickson-si8ww]

the real trick is your on a half a watt transmitter 12 blocks and it's over.

[@olafelsberry9271]

Before you start it's mostly the antenna then next is power output

[@jetseverschuren]

So fun fact, if you look at the European regulations for PMR446, the 500mW limit is actually for the effective radiated power (ERP). That means if the antenna has 3dB of gain, the max transmit power (PEP) can only be 250mW. So even if the antenna was better, you're not actually gaining anything (pun intended)

[@stevewest6884]

The ariels on these things have a loss, not a gain. The radios I bought have an ERP of 500mW, but the actual transmitter inside is 2 watts. When I bodged quarter wave ariels on the radios, there was a 5db increase of field strength and receive sensitivity. This is still a loss, but the radiated power is now 1.5 watts, and the effective range is much improved.

No, that’s reasonable. 4 watts can give you decent coverage but you just can’t rely on it handset to handset. Drop over the slightest crest of a hill and it’s gone. I’ve done some testing with the DP1400 (geni.us/dp1400 ) and it provides a very usable service area.

[@dtv5362]

Given the same power and antenna size, I think UHF 440-470 Mhz has the best range for portable to portable. VHF 144-174 Mhz is a close second. When you go to 800 Mhz the portable range is far less. 27 MHz CB is terrible for portable use, less then PMR/FRS, but has good range with outdoor large base antennas

[@tdcattech]

I'd love to play more with VHF but the antenna lengths are just too clunky for a portable radio on your belt. I feel it should bump up the usable range and 'penetration' considerably. Marine stuff seems to do OK.

Distances of 89 miles are a regular occurrence on 446, but (apparently) 330 miles was achieved from a high hill in England to an elevated spot in the Netherlands.

That is not a budget radio by any means. It is a ruggedised version of their other radios not rubbish. The 10KM range claim is just an advertising con which should be addressed.

[@stevewest6884]

Before I modified my radios, straight out of the box I made a crystal clear 20KM line of sight radio contact. With the modified 1/4 wave ariels I bodged on, a 5db increase in gain was measured on the field strength meter. This equates to a range increase of about 70% plus the increase in receive performance makes them so much better. So, in perfect conditions, the standard radios can easily reach 10KM. Go stand on a hill somewhere, you will be amazed.

[@tdcattech]

I honestly don’t know how radios perform on the slopes as I’ve never used one there. I think the BCA stuff is FRS so no good in Europe. Something like the T92 geni.us/motot92 would be a nice choice.

[@michaeltarek6323]

@@tdcattech Hey thanks for responding it means a lot. Between the T92 or T82 Extreme which do you recommend? Or which Motorola is the best to you? The T800 ?

[@tdcattech]

Motorola wise, I would like to say the T92 but I've just remembered that it takes 4 x AAA. The T82 is much better power wise with 3 x AA batteries. If you replace these with decent rechargeables, it's the difference between a 900mAh battery pack and a 2,500mAh pack. If you want to increase your budget, I love the XT420 geni.us/xt420 but they are pretty expensive.

446PMR is not for you. UHF radio doesn't penetrate solid objects well unless there's a lot of transmit power going on. There are 25 watt units sold, but the battery life if you are talkative won't be good.

[@jaycee7594]

Getting any serious distance on these fixed antenna radios requires a fair amount of elevation - 50 miles from the top of a hill is not uncommon - these type of antennas are OK for close work though and have their place. Forget buying expensive Motorola blister pack radios though! Let's face it, all of these commercial radio packs are offering the same thing essentially. Limited by power/antenna. A £6 Baofeng 888s radio with a £1.Nagoya 771 antenna would runs rings around most commercial PMR sets - advantages are obvious. Better range, more power (2W), very cheap and ability to use the full 16 PMR channel allocation. (Once programmed) Of course this is not technically legal here in the UK but with the regulator OFCOM never putting any resources into policing the band and never bringing anyone before a court for infringing PMR type rules it seems crazy not to . Keep the Bids coming mate

[@skidhvh]

Mr Aphoristic baofeng bf 888 s have 5 watt transmitter ,(of course not full 5 watts ), my tests show that there is about 4.6 watts

[@volkerking5932]

A Radio frequency can't go trough walls! it is every time trough the windows and/or glass doors. 1st problem of this radio is the wrong made antenna. This Antenna is not really in the right length. For example 446.0 - 446.2MHz is the band where it is used for. In the mid the lambda is Lambda(m)=c(speed of light)/f(frequency) => 300000/446.1= 0.672494956288m is Lambda. This is a 1/4 wave antenna => 0.672494956288m/4= 16.8123739072cm - question for all the blind people? is this antenna 16.8cm long? - no it isn't! This is a coil antenna so the energy can't transmit over the air. 2nd a 1/4wave antenna need a counterweight but what is this? 2nd a transmission can only be at full power of 0,5Watt if the counterweight is correct. This can't be because you are the counterweight for the frequency with your hand that hold the radio. Your hand is not metal and this is why you can't emit the full power all in all the power will not transmit into the air. This is the problem and well the urban situation is also a big problem remember the wave can't go trough walls! Best Regards Volker

[@ando5899]

Is there such a thing as a pmr base station?

[@tdcattech]

If using a repeater, yes. The base station would sit on a hill or building in RF reach of all the handheld or mobile units.

Hello you,,good night My rádio have two options:0,5w and 1,5watts made by motorola mr350m

[@Jose-tw9bl]

First of all thaks for the video! great explanation. I wanted to ask about the antena part 5:03, is it possible that you put 1 W into an antena, and 10 W come out? where do the other 9 W come from? thanks!

[@tdcattech]

Not really, however an antenna can focus the radio waves which gives an antenna an 'effective' radiated power (ERP) of 10W. Think of it a bit like the beam of a torch. Same LED, same power but lots of light hitting a smaller area. The trade off is that it becomes directional. This could be in the horizontal or vertical plane or both.

[@Jose-tw9bl]
