This antenna modified to better receive at 1.7 Ghz (cut a piece of pvc pipe to act as a spacer moving the secondary reflector out a bit), rtl-sdr.com v3 dongle, Sawbird GOES LNA & a Raspberry Pi 3 running goestools.
This antenna - https://www.amazon.com/Premiertek-Directional-High-Gain-Parabolic-ANT-GRID-24DBI/dp/B005M8KU3W with a 3d printed spacer to tune it to 1.6ghz, a nooelec goes sawbird, rtlsdr.com v3 dongle, and a raspberry pi 3b with goestools.
You need to get a Grid Antenna like this (I bought the last one :P) and you'll also need an LNA, preferably, this LNA/Filter hybrid from NooElec.
You will also need an N type male to SMA male (depending on the antenna) if you were to get one like mine.
And yes, you do need an LNA for this. Don't be like me, thinking I could do it without one, had to wait another two days for one :P
After that, i'd recommend you get a stand for the antenna to be mounted on, like a modded tripod. I use an old umbrella stand (super bottom heavy) and a wooden stick from a broken broom.
This one looks decent from Amazon... these are getting harder and harder to find at good prices.
I got my last one on ebay, pretty sure it was from this seller.
On to the DC Short thing.... Yes. These are DC Shorted/DC Ground dipole elements for the actual "antenna" mainly for matching purposes. No you can't use it directly with an SDR that has the Bias Tee always on, you either need to turn your Bias Tee off, use a DC block, OR put your LNA in there to use the voltage.
I'm using a SMArTee XTR -> SAWBird+ -> Lorch Bandpass -> DC Ground Wifi Dish... it work's fine. The SMArTee XTR specifically has a self resetting fuse that will trip if you short it to protect the SDR, so no worries there.
I think directional antennas at both locations might do the trick.
