UR0GT Chireix- Mesny Antenna for the 1295 MHz

Chireix- Mesny antenna may be used for operation on 1295 MHz. Design of the antenna is shown in Figure 1.  The antenna has wide pass band- 290 MHz at SWR less the 1.5:1. So it is not strictly demand to keep the sizes as shown in the drawing. Antenna has input impedance 200 Ohm so it is possible match the antenna with50- Ohm coaxial cable with help of 4:1 transformer.

  It is possible to bridge four such antennas to feed the system with 50- Ohm coaxial cable. In this case DD of the system would be narrow compare to one element antenna. Antenna may be made from almost any stuff, copper, aluminum or stainless wire. You may play with model to see how the parameters will be changed depends on the used stuff.

 Figure 2 shows Z of the UR0GT Chireix- Mesny Antenna for the 1295 MHz.  Figure 3 shows SWR  of the UR0GT Chireix- Mesny Antenna for the 1295 MHz.  Figure 4 shows DD  of the UR0GT Chireix- Mesny Antenna for the 1295 MHz.
