Saw this on a website when looking for a Poynting  XPOL-2 
30/09/2020 Update:
We have been notified by Comreg that under the Wireless Telegraphy Act 1926, these antennas are not licenced to be used in The Republic of Ireland for the purposes of connecting into a mobile modem.
Hence we are only permitted to sell this item to users who confirm that they do not intend to use this antenna in Ireland

Do you know anything about this Sean? They can still be bought outside of Ireland.

Would there be much loss with a 10M cable v the 5M on the above aerial, 10m just suits the house layout better.

when would you go for a LOG v a panel antenna?

I haven't come across any publications from ComReg on this other than that message on the website. My guess is that someone has mistaken them for non-compliant mobile phone boosters. There are no active electronics in those antennae. Most 4G routers also require external antenna to even function, such as the popular TP-Link routers (which require external rabbit ear antennae) and the professional Teltonika routers.

It also does not make sense to discourage their use either. If anything, the mobile network benefits from their use. The better the signal quality, the more efficient the cellular modem becomes as it will need less airtime to transmit the same amount of data. For example, if an outdoor antenna improves the router's CQI from 4 to 10, it will need 1/4 the airtime to transmit the same amount of data, freeing up bandwidth for other users on that mast/sector:

I suggest going for a shorter lead length if the signal is very weak outdoors. Try setting up the router temporarily outside to see what the RSRP reading is on 4G. If you don't know which direction the mast is, try the router at each side of the house. This way you will know which side the mount the antenna on. If the RSRP is less negative than -100dBm (e.g. -95dBm), you can go for the longer length. If the signal is very weak such as -105dBm outside, go for the shorter length if you can install the router within that short cable reach. When the signal is weaker than about -100dBm, it is likely to fall below the noise-floor of the router once it travels the cable length.

A directional panel antenna is much easier to install than a pair of LOGs and should be fine in most situations. If the router's SINR value outside is very poor (0dB or negative), the LOGs will provide better directivity and reduce interference from other masts. You will need a long pole or a cross-clamp and a horizontal pole to mount the LOGs, whereas with a panel antenna, you can use just about any outdoor TV antenna or satellite dish mount.
ComReg has recently published a new exemption Order to cover Customer Premises Equipment (cellular routers, antennas, etc.) and User Equipment (mobile phones, dongles, etc.) that operate on frequencies that are used in the state for mobile phone services.

Up until then, only mobile phones were exempt under the Wireless Telegraphy Act 1926. Not even routers and dongles were compliant by exceptions and antennas were only permitted to be sold as part of a mobile phone repeater kit.

Document explaining how things stood:
