# Replace chip antenna part selection ## Problem environment The onboard (compact) antenna selection includes a chip antenna part with several unique alternative models. ## Steps to reproduce 1. Refer to the schematic 1. Locate AE3 and AE5 1. Test and replace antennas ## Expected result The final onboard antenna part choice is the best combination of price and performance available. ## Actual result It's unknown what the best combination of price and performance a onboard antenna part implies. ## Resources In addition to the Johanson 0868AT43A0020E consider other Pulse Larsen alternatives of similar size: * W3320 * W3013 * W3016 * W3136 * W3403 * W3139 * W3000 * W3329 …or the AVX Ethertronics models: * M620720 * 1002427 * 1001011 * LSP69001299TR …or search **several other manufacturers** (for example Taoglas, Linx, etcetera.) ## Severity level This is **low priority** because project requirements do not mandate an antenna choice.
