help with TV ariel

Yes it can help, if the booster is low noise enough so that the signal to noise is not degraded. I bought 2 cheap boosters locally and connected them to a spectrum analyser. With the second booster, the signal increased without affecting the noise too much, so had a significant icrease in signal to noise ratio.
 


Ah ok I'm in the UK and have done freeview aerial installations for quite a few people. What are you getting on the coverage checker? (you can put your postcode here and I'll check if you like, don't need house number)

I would like the name(s) of your available transmitter(s)
