<font size="+1"><font face="Comic Sans MS">There are different kinds
of UAVs. When people use "drone" they usually are referring to
a quad copter which has 4 amp hungry 3 phase motors. The ESCs
(Electronic Speed Controllers), one for each motor are rated at
20 amps each. I use a 3s LiPo which is almost 12 volts. I
haven't measured the true current draw, but it's considerable.
Your duration is limited. If you tried to hover at 300 foot you
might get 10 minutes if you worked on efficiency, maybe more. <br>
<br>
Hauling a wire with a drone IMHO is impractical and probably
unnecessary. Why would you need a copper back haul with all the
neat, cheap WiFi remote controlled radios?<br>
Perhaps it was humor and I'm just a little slow...<br>
<br>
Another type of UAV is fixed wing. They move to stay in the air
so station keeping would have to be a pattern, they could hold
altitude but change position by maybe as little as a 100 feet.
As to endurance a R/C plane has flown the Atlantic

Having a UAV at 400'hold a pattern over an area is entirely
possible. Putting a router in it is possible. It would mostly
be OTS with some assembly required. Within limitations it's
legal. <br>

<pre wrap="">More to the point, how much power does the drone require when carrying the weight of 300 feet of CAT5 cable - which I assume isn't negligible? I have seen folks scratching their heads when they attach a thin antenna wire to a toy helium balloon and then watch it rise to a stately seven feet and stop. :-)

<pre wrap="">Pete -
How much voltage and current does a drone require to maintain a 'steady state' altitude of 300 ft ?
I'm thinking of strapping a Linksys WRT54G router's circuit board under a drone and feeding power up to it via a 200' or 300' CAT5 cable.
