Agreed. But lets be frank here. The antenna and cabling costs are likely to be orders of<br class="">
magnitude more than the shield/hat cost.<br class="">

I have absolutely no problem with that and have paid the price for other radio<br class="">
technologies (such as adsb) and I may well pay the price to deploy Rob's excellent<br class="">
shield. But I think ausnog members benefit from understanding the full BOM.<br class="">
