There was a satellite photo of Wing loongs in Libya. Let me find the link ok?
It's an old picture but I assume UAE is still using it. Wouldn't make sense to make airbase and only use it for a limited amount of time.

ccording to the report the team of experts has issued, Al-Khadim military base which is managed by UAE forces, near the city of Marj in eastern Libya, has witnessed a remarkable development during the period from March 2017 to November of the same year, according to satellite images which have been annexed to the report.
The report confirmed that the size of the southern aircrafts’ apron has doubled, with the paving of the side ground of the airport between two maintenance hangars, in about eight months.
According to the report, the entrance of the airbase has witnessed an increase in the number of checkpoints and buildings which are believed to be part of the airbase’s checkpoints, as well as an increase in the number of fixed vehicles which are likely to be included in securing the entrance, according to Arabi21.
In late 2016, a British website specialising in military matters said the UAE had established an advanced military base in the city of Marj (100 km in east of Benghazi), from which light AT-802 attack aircrafts and drones take off.

International aid to the LNA and GNA has particularly manifested in the form of training, maintenance support and even furnishing mercenary pilots. Egyptian warplanes have flown several airstrikes on behalf of Haftar, while the UAE deployed a mercenary-operated squadron AT-802 Air Tractors (up-gunned crop dusters!) and Chinese-built Wing Loong drones in support of the LNA in 2016. The UAE has also built up large-scale aviation facilities which could be used to support operation by its jet fighters in the future.
