Alternative for iC880A antenna?

@Ideetron, I’m getting 250 meters with your RFM95W, using 8.6 cm solid wire as antennas on (single channel) gateway and node. It seems the soldering is fine (but, yeah, it’s tiny). As the RFM95W does not expose the SX1276 antenna switch (for Rx/Tx), do you think there is any chance I’ve fried the internal antenna switch while everything else is still working…?

[Edit, for future readers: a better antenna and higher location indeed gets me a much better range with the same hardware. See also Best position for a gateway.]
