The Wire Collinear

Gain = 1.9 dBi

Impedance = 54 - j 15 Ω

SWR (75 ohms) = 1.5

Gain = 3.9 dBi

Impedance = 74 - j7.4 Ω

SWR (75 ohms) = 1.1

Simulation results show that Cantenna with Collinear Whip has higher Gain and better SWR, hence should should perform better than 1/4 wavelength whip. I replaced the 1/4 wavelength whip by collinear whip and put to trial run.

**SIMULATIONS****1) Simulation of Cantenna with 1/4 wavelength whip**Gain = 1.9 dBi

Impedance = 54 - j 15 Ω

SWR (75 ohms) = 1.5

**2) Simulation of Cantenna with Collinear Whip**Gain = 3.9 dBi

Impedance = 74 - j7.4 Ω

SWR (75 ohms) = 1.1

**TESTS:**Simulation results show that Cantenna with Collinear Whip has higher Gain and better SWR, hence should should perform better than 1/4 wavelength whip. I replaced the 1/4 wavelength whip by collinear whip and put to trial run.

**The test results were frustrating. The collinear whip performed worst than 1/4 wavelength whip.**
