I was just looking for the length of the antenna's myself (for the 2.4Ghz receivers)
here is what i found out; the length of these HF signals must be 1/4th, 3/4th or 5/4th of the wave length (and so on)
the wavelength of the 2.4 Ghz signal is 125mm
the 3.6" is 3/4th of the 125mm.
I don't know how your receiver is constructed, but i assume the antenna straw is directly mounted onto the case of the receiver, which is in straight line with the PCB;
The length of the antenna is the length of the entire antenna, including the small bit it travels through the house.
Hope this helps. I was looking for an answer on how long the 2.4 Ghz antenna's need to be, and this 3.6" they claim confirms what i've read somewhere else.
