These are a plan C purchase it’s a broadband amplifier with little selectivity I noticed the null for 4G and LTE so therefore tends to amplify all other RF signals being received. Plan A big bright new TV yagi pointing in the right direction Plan B fit decent 75 ohm coax (use the satellite stuff for better shielding). 23dB is probably a touch on the optimistic side given insertion loss more akin to dBi than dBd, so a little trick, putting this as close to the antenna as possible will give you a better chance of it doing it’s job but be prepared for out of band interference.

This is a good product. My roof top aerial failed due to age and cabling and it was too high to take down without an engineer coming out. Purchased a new £20 aerial and placed in loft. Added this tiny little device in line and a further 30 channels became available and now have over 100 channels. Checked on the TV reception checker function that all modern TVs have and it shows an increased signal strength and quality. Buy it from ARGOS, they have 16 day money back guarantee - if it does not work for you then something else is an issue and you can return it. Voted HOT.
Total rubbish I bought because my freeview HD channels been playing up lately this did nothing at all
haven't seen these in 15 years trying to get indoor Ariel more power, lol thank good for online tv
