Keegan commented on bGatti's blog post Could a $5 Sensor and a UAV have prevented the San Bruno Explosion?
"Back to the original topic wouldn't it be easier and cheaper to just have hundreds of small wireless methane sensors all along the gas line. I mean I don't think this would be a very good area of use for uavs."

"That doesn't sound good... I am looking to start an ap business, how much does a coa cost and do I really need it??"

"Not really affordable unless you have 10 grand to spend. Besides my new aircraft can last an hour crusing at 40 mph... When would you need to go 40 miles??"

"No no no, 72mhz is ONLY for RC control, it works very well and no reason not to use it. It will give you back 2.4ghz for the video and 900mhz for data - this is what I use (36mhz for Australia) and it works fantastic."

"Well I do know that the lower the freq. the lower the data rate. Would Keegan still be able to send his video over the 72mhz freq? I thought that's why everyone used the 1Ghz+ range for video and the lower 900Mhz and below for remote…"

"Thank you so much for answering my question. I have another question, is it generally true that the lower the frequency the larger/heavier the transmitter? and another question concerning these transmitters in particular, how do voltage…"

"What about a UHF radio or 72mhz? This will free up the 2.4 band for semi-legal video... at least it would be on the right band ;) 10mw 2.4 works quite good too IMO..."

"Joey, Your second assumption is the correct one. "Power" is the measure of energy output, 100 milli watts or .1 watts will draw the same current regardless of the transmitter frequency. The diference is in how far the RF wave will travel…"

Joseph Reynolds replied to Keegan's discussion This is the Best FPV System for Ardupilot
"Question about this... Is it true that the higher the frequency the faster it drains the battery? for example I will keep the numbers small for easy math: Given a 1000Mah battery and 900Mhz @ 100Mw power = A hours battery life 1.2Ghz @ 100Mw…"
