Hi! I work for Antimedia as grip and drone pilot. We just bought a Cinestar 3axis gimbal with radian to our epic x. Therefore i joined this forum. Is there anyone who has tried Paralinx? We have borrowed one for testing, but it's seems a bit short range, 100m los. Having found that the antenna is in front of the transmitter (the other side of the hdmi plug) I hope to get better range by "aiming" it towards the receiver ?. It has a omni directional antenna. Maybe modify it? It also needs 5v via usb. Guess I will split a usb cable to attach to a ubec when mounted in the gimbal. But if anyone has tested this and know this gives to short range, please let me know. So I don`t have to do all the testing. I have tried it briefly in the office, it works very well. Latency is more than 3ms, but not much. So it will work for camera framing. Does anyone here have a alternative? Weight is most important, not price.. within reason We have tested some Cobham stuff before, but it is a bit heavy.. Link Paralinx: http://paralinx.net/
Is there any provision for an external antenna? If not, the "aiming" an omnidirectional antenna is somewhat contradictory, I'm afraid Daniell. I don't know of an alternative at the same price point. Andy.
No there is not.. I will do some tests. But do you have an alternative? The price of the Paralinx is "to good to be true" compared to the other digital links. The Cobham kit we tested was about 20k i think. But it was on the heavy side..
Hi Daniell: This was the closest thing I've seen:http://www.bhphotovideo.com/bnh/controller/home?O=&sku=800101&is=REG&Q=&A=details The Teradek Cube. Andy.
Going to test the Paralinx next week. I'm more interested in the Teradek Bolt HD http://www.teradek.com/pages/bolt It could be the same/upgraded Hd system but has sdi and will work with Red and the Blackmagic camera. Someone already own the bolt transmitter?
I'm interested in both of these systems as we have a client that is interested in using a live HD feed from our CS8. Please post your feedback as you do your testing.
All, We are using the Paralinx and it's working well so far. I had it for our Red camera so it wasn't an extra expense and it fits great and is really light. Having near perfect HD without much delay is great but it's biggest problem is that when you loose the signal it can take 5 secs or so to re-aquire. I feel like it's a trade off though and I have to say I like it. Bob Wojda
I haven't measured but we only had it drop signal once when I was behind a car. I know that we've gone far enough that we couldn't tell the orientation of the heli, so we came back (we think it was 1500 ft away and 150 ft high according to google maps). I'll keep better track so I can report back later. Bob
1500ft? The most I have got out of the Arrow is about 100 yards. I'm hoping to have a Teradeck bolt (zero latency and 320ft claimed range) system in my hands in the next few weeks. I'm planning on using on the ground, but I bet the range would be better in the air. The bolt tx is bigger than arrow. If I can lift it with my quad, I will let you know how it goes.
How did you get that range? My system only works in about 100m. (50m high and 100m away) How do you mount it?
1500ft ???? wow! i cant get more than 70 meters around 200Feet !!! is there a special position f the arrow? thanks
IMHO, dont waste your time on the Gefen. I have ordered a "arrow" form the OEM for about $200. It should be here next week. I'll let you know how it goes.
Some results on the steadicam forum http://www.steadicamforum.com/index...5eec3dc18cc2&showtopic=16864&st=60#entry82234 So for range it's the Paralinx http://www.steadicamforum.com/index.php?showtopic=16864&st=60#entry82238
Unless I'm mistaken, I don't think anyone has done unobstructed line-of-sight tests that would be the most likely situation for copter-borne situations. Andy.
I don't want to be unrealistic about what it can do but so far the Paralynx really is working great for us. When we use it on the red camera in a regular production it' s more limited in range but that's usually because we're in another room or something. I haven't done a proper test yet, as I've promised to do, I just forget about it while we are busy flying. I would also guess that results may vary depending on lots of conditions. That range by the way was determined by looking at google maps and upon double checking, wasn't exaggerated. Bob
