I want to experiment with different mechanical designs for some Yagi antennas for 440 MHz through perhaps 2.3 GHz. I am looking for some adhesives and/or potting-like materials that would be relatively RF-inert at those frequencies. Can anyone make a suggestion for a material?
Do be aware that when assembling antennas using epoxy, that it can act as a dielectric material. This can affect the primary design parameters of the antenna.
