Assuming a 7 ft monopole, with a lumped element inductor (located in the middle of the vertical) of Q = 500, and 100 W input. The total radiated (sky wave) power is 1.4 W. The gain is -12.7 dbi with a take-off angle of 23 degrees. At resonance the input impedance is 14 ohms. And the Q of a hamstick is probably a lot closer to 50 than to 500. Someone else reported the hamstick as -20 dBd. -- 73, Cecil http://www.w5dxp.com |
