    Designer/Inventor. Speciality miniature SMD PCB circuit design, in-house.
  1. Ok I now have 4 of these Airwave Phase array patches, these are not 4dbi as I previously stated, but are 7dbi #Specs from the factory data state:- Electronic Properties: Frequency Ranges: 5.8GHz Impedance: 50 Ohm nominal Gain: 7dBi(TYP.) Radiation: Patch (not stated.. Weight 10.6gms, with the short coax fitted) I tested a commercial 6dbi radome patch, the Airwave one blew it it out the water by miles. I also hooked up RSSI monitoring to check sig strength on the two patches, again the Airwave one came out top. In 'real' (ground) testing the airwave patch performed very wel
  2. It's a 6MHz ceramic resonator (3 pin type with internal caps) Steve
  3. Airwave make a PCB 5.8GHz patch, not shown on there website, but did see on another RF gear website advertising them for sale. It has 4 square copper area's etched, with what looks like tuned tracks coupling these together. I'll try and re-find it. Looks especially useful for wing mounting I imagine. ##EDIT found the link http://www.nghobbies.com/cart/index.php?ma...products_id=113 Just ordered a couple, I'll test and report back when they arrive.. Only problem, these are vertically polarised and only 4db gain. Steve
  4. Easy way to find ot the paint/Laquer is absorbing microwaves.. spray some on a piece of paper, let dry then stick it in a microwave, if the paint feels hot when removed it's no good. I use Acrylic laquer, not seen any problems with power reduction. Steve
  5. Built many of this TX/RX combo. Managed 1km (10mW) with 2x 8db patches. Just built a 7 Channel 5.8GHz system pair, testing these now, line-of -sight is good, not so hot through buildings. Video quality is very good. Steve
  6. Sorry for late reply... much work and travelling. I can find out for you.. I know the 0.0015 lux version with no Case and outdoors weather housing and wall bracket is about £200. I use 2 of these here for security testing with my IR illumination design prototypes. The 0.00004 version is obviously much dearer, theres an extra digital processing PCB behind the cam PCB.. I'll find out the price, without the case? Your Heli maybe big enough to take the whole camera? I have played with this camera, with a 10 to 1 zoom F1 lens... it's a bit amazing, if theres one light anyware near, the i
  7. I'm gobsmacked You guys are unreal. Watched the video with amazement. The flight was very smooth, much cudos for a risky flight. The camera was performing quite well for only moonlight. If any of you are really serious about night flights? I have a link to some specialist Mil Grade low light camera's these go down to 0,00004 lux, rivaling gen 2 night-sights.. Ultra low-light Cam If any of the more ambitious amongst you tried these cams, you would need the cam module only, as these come normally cased. I would love to see a setup like this Stevie
  8. Slightly related to this sniffer question.. I made a sensor to hookup to my Tektronix scope. The sensor was made from a small ferrite bead (cylinder shape) this was cut down it's length so I ended up with a 'U' shape channel. I wound as many turns of thin enameled copper wire as I could get in. this was connected to a short run of coax and fed through an old plastic pen body, bonded with araldite, terminated with a BNC plug. When used with my scope it's very handy for sniffing out noise. my TDS3032 only goes upto 300MHz, but still fairly useful. Stevie
  9. Terry It maybe fine as it is. Just check if your channel freqs match the above ones of the AWM630TX which I believe are pretty standard. Stevie
  10. Ah ha you guys knew about these modules before me :-) I've posted pics of my TX/RX on PCB's just for info on the AWM630TX & AWM634RX pair http://www.rc-cam.com/forum/index.php?showtopic=993 Steve
  11. Hi It maybe worth a try to take the camera to a model shop? they may have this type plug with wires fitted? I think the type maybe a 'Molex' connector. Did a search through Maplins site, they have an adaptor lead with the mini plug fitted, maybe the one you need? Board camera lead Stevie
  12. Here's one source for camera's, not mega expensive, depends what you after.. http://www.heroelec.co.uk/ccdandcmos.htm I belief they still do the sub-miniature colour RF ones. They can send expanded info on these.. Maplin also have a new sub-miniature colour camera. Link here>> Sub-Min camera Stevie
  13. Just for info: Here's the module side view pic >>
