POTA

In the USA, POTA is very popular. The video shows an operator on a POTA activation trying out a new antenna.

Portable operation

Especially when the weather is good (as in most of the UK recently), many enjoy portable operations with SOTA and POTA becoming popular. 

It is not uncommon to leave something at home, especially if lots are being packed. 

MLS has produced a video recommending some of the products they sell.

Mountain Toppers

 Summits On The Air (SOTA) activity is becoming increasingly popular as well as Parks On The Air (POTA). People climb mountains and hills to "activate" certain summits. Especially for SOTA, weight can be an important factor if the gear has to be lugged up steep hills or mountains.

LNR Precision make some gear aimed at these users. They are compact and lightweight.

POTA with the Elecraft KH1

In the USA POTA seems very popular. Amateur Radio Weekly reports on a POTA activation pedestrian portable with the KH1 and a small whip by K4SWL. 

I don't think the tiny KH1 is available in Europe.
