Ok.. It still weighs 15 lbs. and is almost 4 ft. diameter. Is that $118 for one single unit? What about shipping?
So, let's say you spend $150 on this antenna, which for Outernet essentially will accomplish the same thing as a small patch antenna with LNA, but has to be mounted outside, and requires a fairly substantial mount. It also does have enough gain to work indoors, I would imagine. Maybe make a nice conversation piece in the living room.
LNA & patch antenna = $45 Can sit on the windowsill and work.
Parabolic grid antenna = $118 plus shipping. Can be mounted on a roof or eave mount, or pole.
If you want to simplify the receive chain by getting rid of the LNA, and still have plenty of leftover gain to drive a considerable coax length into the house, this antenna would be the thing to use. Would be interesting to see how a 22dBi gain antenna with no filter would perform for general Inmarsat use.
I would classify this antenna as more of a general L-band hobby antenna rather than specifically for Outernet use.
Why don't you buy one and try it?
