Dipole Antenna for R9M etc 868MHz 915MHz Meshtastic FrSky R9

Antenna T piece for Dipole Antenna. My Antenna was made for an R9M as the stock FrSky Antenna is no way near as good as the TBS dipole.

My antenna was based on https://youtu.be/cJIFynAfG2I with active and GND elements @77mm for 868MHz and I have used RG402 coax with so my 1/2 wave length in the coax inclusing the velocity factor of 69.5% is (C/868MHz) x 0.5 x 0.695=116mm

The youtube video used a print which is thing:2948004 , mine is largely inspired by that so I've classed it as a remix
