بواسطة NimmaS09/04/2018Bangood if you are listening please update the description. This is a circulatly polarised DIRECTIONAL antenna that looks to be based on the immersionRC spironet patch. In saying that is it a good compact, low priced directional patch antenna that works great in combination with an omnidirectional antenna on FPV goggles/screen equipped with receiver diversity.
