FPVlongrange.com 433 Mhz FPV Repeater System

Ground station separation and multi-transmitter control.

Splash

Get some separation between your video antenna and LRS transmitter

The FPV Repeater System from FPVlongrange.com is unique-to-the-hobby device that allows you to remotely mount your 433Mhz LRS and get some distance between it and the video receiver/antenna in the process.

The idea is simple: use the native control-frequency from your transmitter (35/72Mhz and 2.4 GHz), plug the FPV Repeater's input into your transmitter's receiver, and the output to your 433Mhz transmitter of choice. It's known in the hobby that most long-range systems can interfere with video frequencies, effectively reducing overall range. Add in the fact that you are probably not holding your 433Mhz antenna vertically all the time, and now your limiting your control range as well. But with the FPV Repeater, you can now distance yourself, your ground station, and video receiver up to a whopping 3000 feet away (if you felt so inclined). Place the repeater up high and clear of obstacles for increased transmission distance, or outside your house while you fly from inside. The repeater system is well tested with Dragonlink & TLRS & EzUHF systems.

Another great feature is the use of two separate controllers. The FPV Repeater can accept receivers from multiple rc transmitters, allowing you to use one for aircraft control and another for gimbal/camera control.

So this is a 8/10/12 channel PWM to PPM convertter (doable from single arduino mini, with code available on the net) priced at >100$ ?

EDIT: forgot to mention that a simple relay can be made from CPPM capable RX with no additional components by just wiring the PPM output from RX into UHF TX.

thats what 99% would do. just use a ppm rx and you have not all the wiremess (and 100$ bill )

Well I have a few other things on my table but I guess I can copy paste something up unless I find a ready thingy.

no need, if it's cppm you just hook the wire, as he mentioned - there's basically nothing to build..
if no cppm, you buy a ppm encoder,and hook the wire.. this exists, too, everywhere hehe

Misunderstood. I thought they were trying to sell it as their own product. Nvm.

I see now. This would work awesome for the pan/tilt setup me and my brother are trying to achieve. We have a retractable setup that I want to mount on the bottom of my Penguin, so I can fly and he can control it with a separate controller.

Exactly. Using 2 transmitters through a single LRS would help with my long range platform where I need independent camera control on the cheap.

I should be able to whip up a 8ch PPM + 4ch PWM into 12ch PPM quite easily by copypasting bits and pieces of existing code.

A Arduino mini/nano would be adequate as hardware.

I'm looking for the same thing. But my plans require 2 different camera signals...one for me flying and the other for the wife to view and control (she is not that interested in flying, but would love to look around).

Cheers,
Stew

That's what it allows. There are 12 channels for input on the unit. That means all your flight channels are covered (receiver 1) and a few left over for another transmitter to control the gimbal/camera independently (receiver 2). The 2nd posted photo in the article illustrates this.
