Colin Whatley: Thanks Chris. I was thinking I would need to amplify the signal to compensate for the signal loss because the aerial would be 8n the loft, but I guess I could test for signal loss before I buy by taking the Set top aerial into the loft and test for loss of signal. That at least should indicate whether I need to boost the signal before splitting, or just split.
I was thinking of that particular log periodic with incorporated 4 way amp, because it is part of a kit from TLC, including mounting kit, for an offer price of 32, which I think is a good price, don't you!?

Thanks Chris, I have installed the SLX Megaboost 4 way aerial and tested all structured outlets in the house individually direct from the aerial ie. not though the boosted 4 way amp/splitter, and they all get 100% signal quality and strength (which I guess is too much) on the test TV. Unfortunately as you predicted when I connect them through the 4 way amp/splitter they all still show 100% strength, but quality of only 40%, so I guess too much signal!? I've tried a 10b attenuator between the aerial and the amp/splitter, but doesn't improve things much. The log periodic aerial spec only shows a 6b gain from the aerial, but 16b for each output on the amp/splitter.
Is it best to try the variable attenuator between the aerial and the amp/splitter, or shall I ignore the amp and just try a 6 way splitter if the signal is really strong!?
What do you think?

Hello, I have just moved into a new build house with clear line of site to the Hannington transmitter (about 5 miles away). Even with only a set top aerial (Mercury ST) I get a good signal strength (80%) and quality (100%) from Channels on PSB1, PSB2 and PSB3 muxes, but less so on the others (60%/50%), which I guess is to be expected in that they are only transmitted at half the power. I wish to distribute to all 6 outlets in the house.
My question in what main aerial I should get as I have to put it in the loft?
Should it be amplified or just split with the signal strength I have!?
I am thinking of a Philex Megaboost Log Periodic, incorporating a 4 way masthead' amplifier (Which I'll split 2 outputs from).
What do you think?
Thank you.
