I use a multiuse mast. It sits next to the DBS antenna. Its not easy to get to but easy to work on mounted on my chimney second floor. On it I have mounted.
1 - GPS antenna
2 - 1-wire lightning sensor
3 - Dallas instruments 1-wire rain bucket
4 - AAG combo weather instrument
5 - wireless directional antenna
All the 1-wire instruments are using separate Cat5 connections. This mast has been up for 5-years now. I've replaced the AAG combo once because the anemometer screws fell off. The rain bucket is currently not working and I have a second one mounted close to the ground. Pushing the WAF cuz I ran the wires close to the deck and mounted the rain bucket on the deck. Two months ago my AAG weather station anemometer would give me unreal spikes of wind speed close to 80 MPH. For some odd reason (I haven't looked up close yet) it won't go past 3MPH today. It is windy by my home though as one day the fiberglass 24foot ladder that I was using blew down. I had my cell phone with me and called a neighbor to put it back up for me as I was stuck on the roof of my two story home with no way to get down. The lightning sensor is using a shielded two wire coax cable (don't remember the source) but the ground of the cable also goes to the ground spike.
I am in the process of updating the mast (its a typical antenna style metal mast attached with brackets to the side of my chimney) with-
1 - new wind instrument (this time the AAG anemometer quite turning for some odd reason)
2 - pagoda with a HB combo sensor
3 - moving the rain guage to ground level.
4 - may move lightning sensor to the attic.
To date and to my best knowledge lightning has not damaged any of my weather instruments. I've been told that the lightning sensor will work in the attic as well so may move it there. The battery though is still good and I still get reads from it on the counter board in it. I currently have 5 temperature sensors outside and one humidity sensor. 4 -1 wire and 1 HAI temperature sensors. My new setup will be adding another humidity sensor outside. Depending on the time of day the values are close but different.
Ugly as it looks I ran my ground wire along where the chimney meets the house to the ground stake.
I am also looking at wireless instruments now but would continue to utilize my "wired" instruments. The "wireless" instrument mast will be mounted on the other side of the roof about 50 -100 feet from the current mast in a place which would be easier to access. I will take pictures of it.
