[TowerTalk] LP-20 HD Instruction manual

[Tor-Björn Nylund]

Greetings from Finland my friends.

I am still searching the instruction manual for my new-never-used-but-paper-lost DXEngineering LP-20 HD logperiodic antenna. So if any of you even have a glue, where to ask this paper / copy of it, please let me know.
An other question is that what would happened, if I put this log 14-30Mc (36f boom / 13elem.) and CC XM240 (22f boom / 2elem.) 7Mc up, so that the log is in 115 feet and the yagi is 10-11 feet upper. How much they have interaction each other? I know there has been some problems written before, but this XM240 has new design and different boomlength, than the older one (402). I would appreciate if someone could simulate this in the computer and tell me, because I have no programs for that myself.
Third question. Could I add one element for 10.1Mc. to the xm240? how to feed it? Where to put it in the boom to have minimum interaction? Can I put it somewhere bethween the xm240's 7Mc elements and feed it individually? Or should I put it front of the driven elem. of xm240 and drive it as a log? Or as open sleev? How far front?

I hope this is the right forum to ask these Q's. If not, I am very sorry. and I will qsy to Antennex.com. 

73's, Tor Nylund / OH2BV
