maximum range 433mhz
Would this type of antenna work?

How difficult is the PCB layout and matching of a single transistor PA to achieve 100mW output power?
cc1000 transceiver
Using a λ/2 wave dipole would be physically ideal in this situation. What I'm concerned about is the fact that water absorbs RF waves (and all organic things like humans and cattle are about 90% water).
Won't this significantly reduce the expected range? A λ/4 monopole...
433mhz collar
The area to be covered is mostly open space. Typically I would like to get a range of 1000 meters between a tower and a cow, and a distance of approximately 2000 meters between towers (a square array of towers, each covering approximately pi*1000^2 square meters).
cc1000 range
Hi,
I'm currently considering the feasibility of implementing a RF system to monitor cattle with the Chipcon CC1000 RF Transceiver, operating at 433 MHz.
The device will typically be attached around the necks of cattle, making it impossible to use an extruding antenna. What other...
