Investigate attachment of wireless thing, breadboard, IDC connector. Work out what I need to get from Jaycar.
I'm working on an automated radio telemetry project and was after some information/quotes on antennas, transmitters and receivers.
I'm envisioning using fixed directional antenna stations - do you have a list of the fixed Yagis you manufacture? I'm concerned with beam width (not too narrow), gain and cost (since a full scale deployment may need hundreds). What would you recommend for sensing your smallest transmitters at a range of 750m in a moderately dense woodland, or is this too much to ask for?
Also, what're the cheapest VHF receivers you sell or recommend? I imagine I'll aim to end up building my own but an off-the-shelf one will obviously be better for prototyping. Datalogger ability would be good, but at the very least it would be good to have an RSSI output that I can monitor (though if there's an analogue meter I can pull it apart and hook that up to an A/D converter).
I'd also like to buy some transmitters to test a prototype system with. They will not be attached to animals (at this stage) but I would like them to exhibit similar ranges to regular transmitters. Is it possible to buy your single-stage transmitter without a battery and attach it to a AA cell? (obviously it won't require a reed switch) How much would it cost for 2 to 5 units?
Thanks very much! Joel Williams
Their smallest transmitters aren't that small. Write to Titley, who make 0.4g ones
Could you please give me a quote on 2-5 LT4 units? I'd like to use them to test and characterise the performance of a radio telemetry system, so I'd like to get transmitters that exhibit the same range and performance of a 'real' transmitter but they will not be attached to animals and would be ideally operated from an AA cell instead of a tiny battery.
Generally low range (10m) for harmonic. What sort of range did that enormous insect radar get? Hand-held transmitters must be incredibly weak.
Forward supervisor instructions on to Peter Corke.
Ask Vanessa to remind me what the confirmation of supervisory panel and chair involves.
