    hi, i have been looking at amazon.com at IR & RF repeaters. i am not clear if an RF repeater will forward an IR signal.

    this is for an air conditioner remote control in another room, maybe 30 feet away. (ie, can a RF repeater be used to forward an IR signal, radio-frequency to forward an infrared signal). if matters, the air conditioner is: SHARP, cannot see model number right now.

    with all the problems i see on some of the examples. i am looking for what might be the hewlett packard or cadilac name brand for what i am trying to do. thanks.

    i have seen some choices simpler - less expensive than others, but look like require haning a wire over destination IR sensor.. seems myopic.

    would have been nice if you had provided an actual link to the item you were looking at

    not it cannot, RF is a radio signal, IR is a light signal

    (seems rf repeaters have more capability to move rf signals forward)
    (links for work done, pardon not inlcuded, guessing best answer might be an rf repeater, IF:
    inexpensive, easy to use, accurate for what doing, quality enough to work well/ see some bad stories)

    hi, it seemed IR repeaters had some funny issues, the top one seems to be:
    https://www.amazon.com/BAFX-Products-IR-Repeater-extender/dp/B009ZGK6QS

    a simple item might be (WILL THIS WORK?):
    https://www.amazon.com/Terk-Leapfro...1&sr=1-12&keywords=rf+remote+control+repeater

    in doing a search for RF repeaters. do amazon keyword srch: rf radio frequency remote control repeater
    these 2 examples seem clear to show RF used to forward IR signals.
    (not sure if these will work with an air conditioner IR control: think that they would, i guesse i can try asking the manufacturer directly)

    what funny issues are you referring to ?


    ""The extenders convert the infrared signal from a standard remote control into a long-range RF radio signal, allowing components to be controlled from virtually anywhere in the home without the need for additional equipment or wiring.""

    sounds good ..... cannot vouch for their quality

    sane as the one above .... just a different brand


    these are a totally different ballgame ... I have bought and stripped the 5.8 GHz transceivers out of these for transmitting audio/video between hilltops
    for amateur radio amateur TV

    I cant remember if there is a conversion of the IR to RF or not. the 5.8GHz section is purely for the audio and video

    directly: quality.. if they work (or not as some posts state), funny: number of negative posts for items not work / fail.
    indirect: if just RF repeater, worries compatibility? if cables long enough (no listings of cable length), force to skip to idea for IR by RF repeaters.

    is my idea of using 1 of these technically sound for use with an air conditioner (IR) remote. i saw somewhere a claim that "Any" IR signal would be forwarded. (not sure if a function of just that device, cannot find it now).

    but looking then at:
    https://www.amazon.com/Inteset-Wire...6547&sr=1-16&keywords=remote+control+repeater

    or similar:

    cant help with that, haven't used that model


    what cable length ? nothing listed as it is irrelevant. The only cable is the one between the IR detector sensor that tapes onto the front of the device that you are trying to control and the receiver box


    a tricky claim considering at least one of those units you posted stated clearly that some IR signals WILL NOT be forwarded and that was for AV gear .....
    going to something like a A/C ..... all bets are off, it may or may not work, would have to be tested

    if i am correct, think that ad referred to RF signals.. not being forwarded.
    like other post for all IR signals forwarded, (not that i really know better), but would have thought that to be the case.

    only guessing then, some hardware use not obvious to me: "IR only" will require line of sight if required by rx to tx (and cables at tx end to reach far enough, else as thought seen: hardwired all the way in between).

    thanks for replies. that should help. i might try out the 2nd choice above. even if not see direct evidence - may work, for: BlastIR Wireless IR Repeater, By Sewell

    no, the only RF is the link between the 2 units, just doesn't work for the IR remote for some devices

    not quite
    let me draw a basic pic, hopefully this clarifies your misunderstandings .......

    IR extender.GIF

    OK so just to state again
    In the above example the person wants to be able to control the extension speakers in the room on the right
    when the stereo in way down the hallway on the left.
    The IR extender in the right room receives the IR signal from the remote control, they modulate a radio signal
    that is transmitted to the extender box sitting on the stereo. The IR signal is recovered ( demodulated) from the
    radio signal and is sent to a tiny IR LED on the end of a short cable that is stuck over the front of the IR sensor
    on the stereo.
    It is a one way only operating radio and IR link

    hi, thanks. i got all that, i guesse i missed 1 more word in my statement. no worries, i get it.
    also understood from start, chain: IR RX RF RT IR
    (think with all the items reviewing, and some key specs missing i was getting too much other info, re what looking for)

    For quote: if i am correct, think that ad referred to RF ("remotes") signals.. not being forwarded.... says right in ad rf remotes will not work. (is just what meant). safe to say i get everything in this post. i was just head wrapped around an axle for the air conditioner IR remote (vs which repeater to buy). probably better than 5050 will work.

    I have everything i need. thanks for the help
