If you're using a 30' mast, you can use a 5/8 wave or even a 5/8 over 5/8 antenna, and get quite a bit of gain. Get gel cell batteries if possible, but definitely put whatever battery and equipment you're using into some kind of box, preferably waterproof. I use milsurp ammo cans for a lot of projects, and drill/punch holes in them for the fittings. My next possible project is a WiFi repeater in a can, with a couple of gel cell batteries in the bottom, a non-conductive
separator, then the electronics compartment with the AP, and antennas on the top, with fittings on the side for power and ethernet. <br><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">----- Original Message ----<br>From: Doug Ferrell <kd4moj@kd4moj.org><br>To: TAPR APRS Mailing List <aprssig@lists.tapr.org><br>Sent: Wednesday, February 14, 2007 8:06:35 AM<br>Subject: [aprssig] Solar Power Temporary Digi<br><br><div>Greetings:<br><br> This is probably redundant and asked 1000 times but I've had a harddrive<br>crash and my aprssig folder is trash.....<br><br> We have a bicycle event in April and need to set up several temporary<br>digi's on some 30ft mast along the route. What I would like to do is<br>probably have some with solar capability (deep cycle battery etc).. so any<br>input on the least expensive way to do this would be appreciated.<br><br> The event and prep would probably cover
about 60 hours so maybe a<br>deep cycle battery at half power on the radio might work...?? <br><br>-- <br>...DOUG<br>KD4MOJ<br><br><br><br><br><br>_______________________________________________<br>aprssig mailing list<br>aprssig@lists.tapr.org<br><a target="_blank" href="https://lists.tapr.org/cgi-bin/mailman/listinfo/aprssig">https://lists.tapr.org/cgi-bin/mailman/listinfo/aprssig</a><br></div></div><br></div></div></body></html>
