25M of Webro HD100 (the correct cable to use) would only loose an extra 4-6db or so so IMHO the HD box can handle this unless the signal is very marginal to start with.

Salient part of datasheet below:



You can get a 25M length with 4 "F" connectors here on Ebay for £25.49.

IF you get the cable try connecting the entire length into the box BEFORE you install it perminently. There's a status page in the tech part of the box setup where it shows you the signal strength, compare the before and after values. Someone with better tech knowledge than I can say what the worst case value is for the box to work reliably.
