No I mean they're on the back of a turtle who only has one flipper left and blind in one eye. Still no ETA.

I've seen such setups with clients in trees and signals right around -69 on both chains. Not a lot of aggregate capacity per sector however.

Make sure you jam the probe into the interior of the thing. I am guessing that the water content of the needle absorbs some of the RF energy al la a microwave oven. But anecdotal evidence over the past 10-15 years has shown that pine trees are worse than others so if the needle itself has a fairly low resistance, like 100 ohms, it is acting like a dipole with a termination resistor. That is really going to suck up the signal. Stealth aircraft have microwave absorbing foam on some of their surfaces that operate by similar principles.

Ponderosa pine needles (and many other pine needles) are around the same 3 1/4 inch length https://en.wikipedia.org/wiki/Pinus_ponderosa so with water in the needles you have a big 900Mhz RF scattering/reflector ;-) -Sean On Wed, Feb 17, 2016 at 1:47 PM, Sam Lambie <[email protected]> wrote: So if you have a minute to please explain how evergreen trees are terrible on 900 mhz, I would greatly appreciate it.
