I've been thinking > about adding the 10m reflector. Questions: > > 1. Is it worth it in terms of gain, pattern, etc.? YES YES, You get just less than 1 dB of additional gain AND the f/b increases dramatically. I converted my C3s to C3E and strongly recommend either the C3E or the conversion. > 2. Can the element be installed while the antenna is on the tower? Assuming you have the boom to mast at 100.5", you MAY be able to reach the position for the reflector as it is mounted at 65" from the 20 meter reflector end of the antenna. Please be safe and do it on the ground! > (reaching the installation point from the tower) > 3. Are there any adverse effects on the other bands (20/17/15 and 12)? None. > 4. Where exactly does the 10m reflector go? I assume it's going between the > 15 driver and the mast or just behind the mast. 65" from the end of the boom and between the 15 meter reflector and the mast. > I have been able to take down and re-install the 15 driver to adjust its > length, so if the point for the 10m reflector is reachable, I'm sure I have > the dexterity to install it on the tower. Yes but the 15 meter driver is only 19" from the mast. Take it down and do it the safe way.
