If you are planning to replace the original antenna in Taranis don't use RG178 or RG316. There is a much better solution! The RG405. RG405 is designed to go up to 40 GHz while RG178 and RG316 are labeled up to 3 GHz. With that in mind be sure that RG405 will perform much better at the 2.4 GHz at what Taranis radio operates. If you don't believe check it for your self: https://www.pasternack.com/images/ProductPDF/RG178B-U.pdf https://www.pasternack.com/images/productpdf/rg316-u.pdf https://www.pasternack.com/images/ProductPDF/PE-SR405TN.pdf In this datasheet, there is only 1 GHz test that we can use to compare cables. Here is the table: Name            Max freqency[GHz]          Attenuation at 1 GHz [dB/100m] RG178 3 145.7 RG316 3 124.67 RG405 40 72.18 From the table, you can see how RG405 has much less attenuation at 1 GHz then RG178 and RG316. Less attenuation and Teflon...

Recently I was looking for a small lightweight, at least 6 dBi gain antenna. At mouser web page I have found 25x25x4 mm patch ABRACON APAKN2504-S2448-T antenna for PCB with 7 dBi gain. I was surprised by this very nice antenna design. So I order two of them. When they arrived I was not sure how to connect to WiFi device so I started googling. There was no any special explanation how to connect it on the 50 Ohm cable, only how to connect it with 50 Ohm impedance PCB link. So I decide to connect it this way with 50 Ohms pigtails. After I connected it, I have tested it with a WiFi router, and they work very well.
