WebOperating Frequency Considerations (Focus on Sandwich Radomes) A-Sandwich radomes can be tuned if the foam core thickness is varied for a particular RF frequency to achieve a desired insertion loss. Insertion loss reduces the available signal, decreasing effective radiated power and G/T (the ability of the antenna to receive a weak signal). Webdesign allows for panel assembly to take place inside the radome and easy panel removal for re-placement or repair. Military vehicle image courtesy of Thales; shipboard radome …
