Subject:  dipole vs. Mosley TA33-SR Author:  Peter Larsen <ve6yc@shaw.ca> Date:  10-May-2003 09:44:38 First off let's assume the antennas are all at 48 feet over real ground. The di-pole is of unity gain. From the triband report: TA-33 has average gain of 1.2 dBd and peak gain of 1.5 dBd C-3 has average gain of 3.3 dBd and peak gain of 4 dBd So why the change from 52 to 59 on the report? Well two simple factors. One, S meters are not very accurate, and was it a reading of 59 or did you just sound a whole lot louder? Some set ups sound like 59 when the meter reads some what less. Two, angle of radiation. As you add in elements to a di-pole you will lower the angle of radiation. Did you bring more of your signal into the best receive/transmit angle of radiation? There are times (very rare) when a di-pole will be equal to a TH-6 on receive depending on your angle of radiation. This is why lots of antennas at lots of heights make for a better contest/DX station. Just some thoughts to add to the stew.
