Does anyone know how these compare with the TureDio model TD-220 RF units? Would it be better with radio frequency rather than the infrared?

The TD-220 RF units have a digital component already built in. They also do not require a direct line of site and real time audio is transmitted to the headset using 2.4 gHz radio transmission allowing users to walk from room to room and hear uninterrupted sound.

I don't know if radio frequency is better but my parents that require hearing aids say these are the best product they own. If you do turn away from the transmitter you do lose the audio until you turn back.

I can only reinforce what others have said - they work very well for older people with hearing problems.

Wow. Congrats on stepping into the field. I have the B/H the 1080 HD. I would recommend if you can afford the ful spectrum to purchase it. But if you are just starting out you may want to go with basic infrared. Make sure it is something you truly want to peruse. Full spectrum has many uses but also has its flaws. Look me up on Facebook @ Kalkaska Paranormal for further help.

The radio comes with a small Dipole ant that works OK, but as long as you can get a bare stripped wire of about 1 meter in length, that should work just fine for most appl. If you need to bring in far away FM, I would go with on of those outside UHF/VHF/FM ant, because they are all close in the freq. spectrum. FM is usually pretty easy, you can spread a flat ribbon 300 ohm cable, stripped, 18" to one side and 18" to the other taped on the wall. Have fun, Gary.

Welcome. Glad to help. The performance to cost ratio on this RF transmitter / receiver pair is exceptional, in my opinion.

I agree with Chris, I've only used the RF transmitter to broadcast the sound the radio of our vehicle. The IR should work just fine.

I can only share my experience but we live in a town that is not saturated with RF, I can hit one of our VHF repeaters from about 5 miles away, I bought this a test tool while we were doing our narrowbanding project. from our Landfill (5 miles away) I could hit at least 2 repeaters, did not try the other. Again these were both VHF, I did not try our UHF as that is public safety. I like the fact that I can test all of our stuff (UHF and VHF) with one radio. Not familar with an ht202 so can't help compare.

I purchased one of those systems, but I returned it. I found the UHF signal to be a lot better. I do not sell them either.

Yes, if you have the emitter and plug it into the back of the tv for rf, these need an external emitter but rf is better imo.

You will have to buy their RF glasses (about 100 buck each) OR you could get a Dimensional Optics 3ACTIVE IR Emitter (25$) and buy IR glasses ( I recommend the Sony Playstation glasses, they are CHEAP CHEAP and super comfortable!). I have that setup and it works perfect (you can get PS glasses refurbished for about 6-10 bucks each!)

Depends on the material. Typically lower frequencies, 2.4GHz or 900Mhz are better for that. In any case these radios are designed to have an open fresnel zone and won't operate optimally even if you manage to get a signal through.What are you looking to pass through? How many walls, what's the building material?

I bought a second unit for my son as a gift. He also is very pleased with the performance compared to the infrared type motion detectors. The alarm has a type of distinctive chime that last about 2 seconds and can be heard throughout the house. In fact our dog adds to the alarm by barking and going to the door in anticipation of a visitor. In case you missed the audio alarm a red light on the receiver turns on until reset indicating that a vehicle has been detected in your absence. The red light does not need to be reset in order to receive another audible alarm.o. Laug

I think the only difference is the mounting style and the amplifier style. Other than that everything else is the same. I also bought some rabbit ears, as they were pretty cheap. My personal opinion is that the rabbit ears perform just as well, so would purchase them over the Terk FDTV2A if I had it to do all over again.

Same thing here. Two 888LMs both work great, except the motion detector that results in lights turning off only momentarily, and then turning back on almost immediately. It is motion detection, only without motion.

Don't know about the others, this one is very good. Bought it for my aunt who lived far out in the country. She could view stations over 100 miles away. UHF or VHF, I think they're all digital now anyway.

On a watt meter UHF output is just about exactly 4 watts on the high setting. I ended up going with a Diamond SRH805S stubby since I wanted this HT for UHF use anyway and I can say that the combo, even for a stubby and only 4 watts, is impressive as far as true distance is concerned. The stock antenna is not going to impress you for UHF IMO. Ron, W2ZXL

Hi TBC. I've never run more than 2 of these units at the same time, but I think as long as you set the frequency of each unit to a different available pre set frequency (there's a choice of many -- 20 or more?-- built in to these babies), you shouldn't have interference. Of course this supposes that the space where you're using them doesn't have native RF or frequency noise happening within any of the frequencies you set your units to. I have yet to get much external frequency interference or noise in the frequency ranges at which these units operate. Good luck.

Try a 27Mz rubber ducky..These Antennas are closley matched to 162Mz.... Reserched.... (wheather channels) This is why the wheather comes in with more clarity..QUOTE}There cute little radios.But not Quite up to par for mobile use 4 watts! Not)Try 60MA! Good for 100 feet!
