I use one just like auction #180518378555. It is "only" 26dB but the thing is very reliable. It is a helix antenna inside and the mounting holes on the bottom line up with a standard iron pipe flange so mounting is easy. I filled the flang flat them glued autommotive type gaskit mmaterial to the pipe flange and attached the antenna with four stainless steel machine screws. The "N" type connector makes it waterproof, The rg-8 style cable is totally inside either the iron pipe or metal conduit so it should last forever.
One idea: Possible the ultra-high gain antenna is over loading the GPS receiver. 50dB is very high Another idea: If you want gain buy an in-line ampler of the type made for satelite TV dishes. The specs are "close enough" that it will work and they are inexpensive.
