Satellite Receiver LNB Out to TV Antenna In
With my parent's previous box (the Strong SRT 4620), there was a TV antenna out port. This allowed them to also watch Satellite TV from their bedroom via a long running TV antenna cable.
The Strong receiver has since been replaced by an Openbox S9. The Openbox S9 has an LNB Out port, but it doesn't have a TV antenna Out port. I bought an F59 to TV adapter from Dicksmith:
thinking that it might work. However, I am not getting any signal on the TV. Does anybody know how to make this work? If I can't use the F59 plug to TV adapter, is there any other way to do this? I take it that there is no such thing as a RCA video to TV antenna adapter?

You can't get RF out from the LNB output on the receiver!!! Disconnect it as you may damage the satellite receiver.Originally Posted by kazzer

Jaycar have a couple of different models.

The antenna out port on the Strong was a modulated AV signal.
The LNB loop out is just that... an LNB connection, not a modulated output of the box.
Do not connect an LNB out connection to a TV antenna input socket, as it may have damaging voltage present.
What you need is an AV modulator fed from the AV outputs of the box, or connect the AV cables direct to the TV, which has better picture quality too.
You could also use a VCR to modulate the AV signals.
Good thing I asked. I will disconnect the F plug adapter tonight.
I ended up getting the following RF modulator from Jaycars:
I hope it works. Will try it tonight.
As Leroy has stated, there is no modulator and hence no RF Output on the Openbox S9 receiver.
However, you can accomplish what you wish by using a VCR.
Using an RCA cable, connect the VCR (Audio/Video In RCA connectors) to the Openbox RCA Audio/Video Out (or A/V Out on one of the Scart sockets using an RCA to Scart cable).
Then, connect the existing extension cable from the bedroom to the RF Out connector on the VCR.
Obviously, you will also need to retune the television receiver in the bedroom to match the modulator output channel selected in the VCR.
The VCR will need to be set to the appropriate AV input and also switched On when viewing in the bedroom is required. (It won't work if the VCR is in Standby mode).

Openbox outputs.
G'Day Cobber,
Page 6 of the User Manual will help you.
If you need a full copy of the manual, let me know.
The LNB out is for connecting to another Box.
There are 4 outputs you can use, CVBS, Pb, TV/VCR and HDMI.
The CVBS is more or less the equivalent of the RF out connection that you were previously using. Need to scan the TV to find which channel.
Kindest Regards, " The Druid ".

This is raw Video and will not "scan" in on the TV.
All the other posts before this have been good advice.

Uh Oh Oooops!
Dudes rush in where Angels fear to tread.
I would suggest that you read this on page 20 of the manual before you say "Oops, sorry "
Kindest Regards, " The Druid ".
Where's the TV RF Output port on the Openbox S9 as mentioned in the manual?
If the CVBS is the equivalent to an RF Out, does that mean I don't really need a modulator, but just an RCA to Coax adapter?
CVBS is a composite out output not an RF out.[COLOR=Blue]I would suggest that you read this on page 20 of the manual before you say "Oops, sorry "

I would hook up your RFModulator and enjoy the TV program
In your earlier post of the user manual it states "CVBS: connect tv through RCA"I would suggest that you read this on page 20 of the manual before you say "Oops, sorry "
Kindest Regards, " The Druid ".
I suggest you read both of your own posts, decide which one is correct before you say "Oops, sorry".
Go to Google Maps and click “Get Directions.” Get directions leading from China to Taiwan, and look at instruction #48.
Ok, I've hooked up the RF modulator and am able to get a signal on the TV. However, I am getting a distorted image and no sound. Is there any particular setting have to set on the Openbox to fix this?
Hmmm .... it seems that a little clarification is needed here.G'Day Cobber,
The CVBS is more or less the equivalent of the RF out connection that you were previously using. Need to scan the TV to find which channel.

CVBS output is NOT analogous to the RF Out signal, which we are discussing. CVBS refers only to a composite video signal - there is NO audio component.
For a description of CVBS see the Video Basics section of the article at .
Composite/CVBS Interface
Composite signals are the most commonly used analog video interface. Composite video is also referred to as CVBS, which stands for color, video, blanking, and sync, or composite video baseband signal. It combines the brightness information (luma), the color information (chroma), and the synchronizing signals on just one cable. The connector is typically an RCA jack.

You must be reading a different manual, as I have searched in vain for that in the Owner's Manual, which came with my Openbox S9 PVR satellite receiver.I would suggest that you read this on page 20 of the manual before you say "Oops, sorry "
Kindest Regards, " The Druid ".
Additionally, none of the Openbox S9 PVR receivers I have seen have had an modulator or RF Out connector installed.

I couldn't find it in my manuals either.
Composite is composite not a substitute for an RF out.
Lets see when beer4life sobers up if he comes back to appoligise for his belligerence! LOL

The jaycar website sais it needs a power pack:
- Requires 12VDC @ 100mA
- Use our plugpack MP-3147
Did you get?
OR
It could be on the same RF frequencey of another device that is causing interferance. Try disconnecting any other devices that have RF in/out from the system.

Question asked, answered in the first two replies, then in comes "The Druid" to help out.

Many years ago I tried using one of those modulators, but without success. The ones that modulate in the UHF frequency are the way to go. If I was you, I'd return the modulator and go by the vcr method described above - you shouldn't have any problem.
kazzer (06-06-11)
I have been through all this with my DM500.
I tried a Jaycar modulator and also got a distorted picture.
Solution?
Run the RCA outputs into a old video player then use the RF output from the video player.
Edit, sorry, already mentioned in post 5 by Tristen,

It looks like the problem is with the Jaycar LM3872 RF Modulator, which modulates in the LOW VHS frequency. I tried Tristen's suggestion with an old VCR and that appears to work OK. The VCR is ok as a temporary solution, but I would prefer a something smaller. I am going to return the modulator tomorrow. Has anybody tried any of the other RF modulators for Jaycars:
or this item from eBay:
