The Log 36 (pre wired) is the correct aerial in medium signal areas for any transmitter (also see Yagi 18K).
There is more than one model of Log36 on the market, and I have tested at least one other.
Unfortunately they don’t work as well…..
The aerial come with a clamp for poles up to 2in.
NOTE 2: The version sold from Jun 18 on, is, unfortunately, pre-wired. In order to improve the waterproofing of the F conn joint we supply 1ft of self amalg tape.
The Log36 is supposedly tuned to help reduce interference from the mobile phone signals transmitted just above the TV band since 2013 (though it must be said a filter is generally the most effective way to combat that problem). Log36s are only available in T group / wideband.
See wiring up a Log36.
We recommend that for outside installs all Log Periodic aerials tilted up at the front end.
