This is redesigned by us TFP-1 patch antenna - we called it TFP_T (T-means Tiny).
Diameter of antenna is only 46mm. This is great choice as goggle antenna.
This is one polarization version so there is no need use SMA terminator - as is needed in Hybrid version.
Available in LHCP or RHCP version. Due smaller diameter of reflector gain of antenna is about 8dbi, but it has slighty wider beamwidth.
Orginally TFP-1 was designed by Maarten Baert and Robin Theunis and credists goes to them :)
We designed our special tool for faster and more accurate assembly.
Accuracy of assembly our TFP antennas is in about +- 0.02mm.
This is highest quality TFP-1 antenna on market.
