Ask HN: A mobile antenna uses 15kw. It seem's a lot. Does someone know why?

  From what I remember (I retired 10 years ago) in 3/4G it's more 400W. https://5ghub.us/5g-transmit-power-and-antenna-radiation/ https://5ghub.us/5g-transmit-power-and-antenna-radiation/ With (real) 5G there is a need for multiple antennas because of MIMO and much shorter range where only one was needed before, so maybe that's what you refer to?

  A mobile antenna uses 15kw. It seem's a lot. Does someone know why? Can you add more context to this? The most I've been able to push through a mobile antenna (HF) is 5000 watts. Finding mobile antennas rated for more than 5kw is challenging.

    Sorry, in fact, I meant base station, i.e. 3 antenna and equipement, powersupply, network, microwave ...
