Hi guys, i need a RF awitch like this,

But 5inputs and one output ,thanks

Re: RF Switch!

I have some like this:



Never seen one with more inputs than that.

What are you trying to do? Hook up your Pong, ColecoVision, Atari 2600, Commodore 64, and Atari 7800 consoles all without swapping cables?

I need to redistribute 4 or five outputs like 1 VCR 2 sat outputs Chan 3.Chan 60,1 converter box all to one cable to the hole house,don't have payed provider have OTA and FTA and i collect Chan 3 and 60 from my brother in law 2 cables coming from downstairs.

note =that i use 5 cables and a splitter and every time i want to change chan to the other tvs in other rooms i change the cable input which is not the same if i had a multi push in switch and there would be less loss of signal

Right- you'll avoid the loss thru the splitter.

This is probably not what you want to do, but what about using the A/V line outs?

Re: RF Switch!

Sounds like you need a UHF modulator (or several) to modulate each source onto its own channel (no running downstairs to push buttons). Then you split the output of the modulator to all your TVs and they can tune each source independently as its own channel. I have this setup at my house and love it. I combine the OTA antenna (DTV channels) with the output of the modulator and pipe that to each tv (currently 4 DTVs and 4 analog TVs) The digital TVs get all the OTA channels plus the 3 in-house channels (65: security camera dvr, 67: TiVo, 69: XBMC). The analog TVs only get the in-house channels. Here is a generic diagram:

I apreciate your info but need something more like

https://www.badcaps.net/forum/showthread.php?t=18544

the RF coaxial switch shown above wish it had 1 or 2 more outputs because all
the inputs are coaxial RF outputs coming from deference receivers and have to be separated otherwise they will have interferences from mostly the sat signal same Chan

Re: RF Switch!

I've never seen one with RF connectors with that many channels.
.
I have seen them with RCA and/or S-Video jacks with that many channels and they have RF-to-RCA adapters. [Or you could modify it by changing the connectors.]
.
Alternately you could modify [change the jacks] in a KVM switch.

Re: RF Switch!

you can at least combine some of the inputs with a diplexer first to reduce the requirements on the switch. For example, you can combine the satellite output with the OTA.

The freq is rf after the receivers ouput and are all the same freq

I thought of that i have a RCA push button video Switch with 5 outputs 1 input maybe if i modify the RCA to coaxial connectors it'll work?

Re: RF Switch!

No need to "mod" anything. Try some of these:

Keep in mind that a baseband switch may not shield or isolate enough at RF. The carriers are 61.25/67.25 MHz for CH 3/4.

If it's something like this (metal), give those adapters a try:

I'd personally make something out of a Hammond aluminum box, some F connectors, and a decent switch. A proper RF switch, with good characteristics (insertion loss, isolation, return loss) is more expen$ive for a reason.

Re: RF Switch!

Yes i have one similar to that

That's what I said in another later post.
You'll only need some of the video wires.
.
You could just make you own from scratch too.
If you get noise/static just put a filter on the output jack.

I hoked it up and and connected 2 inputs and i had i lousy pic with crossover and weak signal, i have a clean pic just by inputting cable by cable individual so i will keep doing it unless there is a better way,

the Modulator and the schematic shown in the in the other prier post sound good if i can get a clean pic on all Chan output,remember my TVs in all the rooms that i want to feed are all analog i have 8 of them.

Re: RF Switch!

Connections make noise and add resistance.
You need filter(s) and an amp.

Re: RF Switch!

today i dicovered that this video switch also does Rf conversion,i though it did not work i was using a rf converter connected to it.
