I am looking at getting a handheld UHF to cover two purposes. As an occasional caravanner, I see the value in being able to talk to the truckie wanting to pass me and an occassional G'day to other vanners. I also have a sports car and go on club trips where some also have radios either handheld or fixed and it is usefull when travelling in convoy to be able to talk to the group leader or the car directly in front etc. Because I want to take the radio between my two cars (and dont want to have a UHF aerial on the sports car) I think a handheld will suit me better than an under dash unit. I only need a range of a few kilometers so dont need 5 watts of power. Would 1 watt be enough for my purpose, or 2 watts of what watt?! I might also ask if there is any real advantage in having a seperate mic with a handheld. Thanks everyone.

for the purposes you describe, reckon you could get by with 0.5W get a pair (cheap backup if you like) for around $50.

We lend out 0.5 watt to friends and they are usually a good 1-2km in range on the open road. We tell them to put the handheld up high so the aerial works better - on the dash or hanging off a grab handle, rather than between the seats.

Do the 0.5 watt units have reasonable sound clarity in both rx and tx? I can't imagine the sound from such a tiny speaker would be either loud enough or clear enough. I'll take you word for it if you say it is though.

I think it varies.Mine are the Uniden UH040R which were the original 0.5 watt handheld and they are excellent for clarity. I've seen some very small ones like the UH036 that are not as good. I can't speak for any of the many other 0.5 UHFs around.

I have not noticed much variation in the size of speakers in any of these hand held sets. At any rate, there are many more design parameters that effect the quality of output than just the diameter of the speaker.

Just remember that handheld uhf radios have their range greatly reduced when used within a vehicle due to not having an external aerial.They are really designed to be used outside a vehicle to get the full benefit of their limited power.

Hi David,

Go for the highest power output you can afford. Even though you say you only need the range of a few kms, in hilly country the 5W would be the only reliable radio.

Also there may be a need someday when the higher powered radio could help you in a predicament.

Regards
David

Hi David

Theres more to good communication than just the power , in another recent thread I reccomended a mid range unit and I think that applies in your case also.

--------------------------------------------------
Their are some significant differences amongst UHF handhelds and some of these features are needed else the units can be a pain.

I would reccomend you consider buying The Uniden UH065sx.

This is a mid range unit that can be brought as a single or twin pack.

I have probably some 20 or so uhfs yet still brought a twin pack recently for our Simpson bike trip (Ebay $229)

It has a really nice set of features that make it very handy. These include a rotating volumne control (not up/down buttons) , and a 3 position settable mute control which makes it much easier to maintain comms with someone local.
It also has the ability to transmit only (not receive) on Vox.

I.E. It can be left in a car and transmit when a loud noise is heard and not give its presence away.

The twin pack comes with both earpiece Mike and speaker mike which is really valuable for bike work.
Leaving such a radio set up in a mobile phone holder on the dash such that the aerial can see other road users and using its external mike makes for better all around communications.

The CTCSS feature also works well - and we would never buy a unit without this.
It even has settable call tones, and a relatively easy to use menu structure.

Whilst power is settable up to 2 watts (we often use 5watt units) , this 2 watts is from their supplied rechargeable batteries.
When serious - as per recent trip - we use those expensive lithium
AA cells instead and this makes the radios deliver more power and last a very long time whilst also lowering their overall weight.

Thanks for sharing your knowledge Robin. Actually the Uniden UH065SX is a model I have shortlisted when looking around the various websites. generally available for a tad under $150 it seems like a good investment.

I take on board though other comments that the aerial is just as important as the power and I will see if there is a longer aerial that can plug into it. Is there a magnetic base unit available?

I am actually going on a sports car club trip this weekend so will see what the other guys are using. I know there is a mix of hand held and fixed radios.

You may be surprised to know that many of the Mazda MX-5 owners I have come across are the same age as us caravanners! Just a pity the car isn't really a towing machine!

Cheers

David

Hi David

I was thinkig of the quality of the audio as well , these mid range units don't have external antenna's although there is one cheap 5 watt ebay unit that does.

As long as the antenna can see out the car it will perform reasonably well and for this reason we like to use mobile phone holder up on the dash to ensure this happens and external Mike so that the antenna signal is not distorted by someones head.

Have fun on your sports car trip - hope you don't have the same problem as my mate did the other week when they opened a new road called eastlink here - his ferrari was part of the opening parade and it was almost impossible to keep the thing down to average 20kmh and he spent much time de-coking the engine afterwards.

Bought 3 hand held 1 watt u-beauts from Aldi 70 odd dollars. With charger and vox (voice activated). Do the job. 3 km line of site (no hills). Shop around. Specials available nearly every week at various stores. Use the KISS principle. No need to go overboard. Advise received is sound. However, Common sense should prevail.
Cheers

That's interesting. I assume that was $70 each! How long ago did you buy the Aldi units? They seem to have different items each week, never to be seen again. Sometimes their special items are somewhat unusual (was almost tempted to buy a good looking Aldi trumpet once for about a hundred dollars just for a novelty - glad I didn't actually in case the grandkids come to visit!).

I take your point about KISS though as I only need occasional use but at the same time I want to be sure it will do the job and have reasonable clarity in both rx and tx.

I might explain too that the convoys I mentioned are up to thirty vehicles long. With a bit of stretching between vehicles, that can be a few kilometres in itself. Hence I don't want to be underpowered.

Thanks again
