    Oh, I quite agree! And I'm quite thankful for your design, it's what made me try the ebay ones ;) Jus thought I'd mention those, since I couldn't find anywhere mentioning if their good or not, turns out they are! :) And their 5 for 1 dollar, so pretty cheap! In fact I chose them cause it was cheaper to get them then to order some bendy wire XD (Not much of a DIY scene in this country, and seems solid core wire isn't as common on ebay).

    Just as a note, the cheap 'Helical antenna 433MHz' for 5 a dollar on ebay actually work quite well too (not surprising, their very similar in design, 21 ish turns of 5mm ish diameter, so that's about 33 cm in them, + 1 cm at the straight end) :)

    For anyone reading this and looking for good antenna advice, I've found that the tiny 'Helical antenna 433MHz' ones you find for 5 a dollar on ebay actually work reaally well, using one of those with one of the cheap green square transmitters has put me from a few meter on the same floor (with ~17cm wire) to all over the house, all three levels, and the shed outside :)
