    OK I was to impatient to wait a reply so I gave a try. I reversed the polarity on the aerial motor and on the limit switches! Now on is aerial retracted (door open) so what power the relays are using is being replenished by the solar panel. Why go to this effort when you could just use a bigger battery and a bigger solar panel? Well it would be more expensive so you may as well buy a ready made door opener. Plus like I said on a previous comment I wanted mine to be tidy and compact. My battery is the size of of a 9v battery about 1 x 2". I hope I was able to add a little something to an already fantastic design :)

    has anybody managed to get over the power drain from the antenna being extended? I made one myself but it didn't last through the night. I adjusted the limit switches on the antenna to just the right amount to keep everything tight and compact so I really don't want to use two timers or a larger battery.

    How about stripping the antenna down and swapping the plus and ➖ to reverse the polarity so in theory when the relay is energised the antenna will retract instead, that way when the relays are drawing power it will be day time and the battery will be getting replenished by the solar panel. Or am I missing something?
