5.8 GHz link to house

[ChrisM]

I recently had occasion to set up a wireless video link from the observatory to the house. This allowed me to show some elderly visitors the moon on the large flat-screen LCD TV in the house. They were absolutely fascinated with the view, which was about 6 arc minutes, and even though it was mainly a static image, it was like they were waiting for another meteor to strike the surface! Gripping stuff!

I stopped short of controlling the scope from the house, but did do a 3 minute lap of the moon from the obs for them.

I used a 5.8 GHz wireless A/V sender from Jaycar http://www.jaycar.com.au/productView.asp?ID=AR1880&keywords=5.8+GHz&form=KEYWORD (http://www.jaycar.com.au/productView.asp?ID=AR1880&keywords=5.8+GHz&form=KEYWORD)

It took literally only 5 minutes to set up at each end, and gave a virtually noise-free picture in the house, which is about 20 metres line-of-sight from the obs. I'll definitely be doing this again and may investigate whether I can connect an external antenna to the transmitter unit.

Great idea:)

I like the fact it's not interfered with by the other wireless networks because of the frequency it operates at.

Carl - Yes - it's well away from the 2.4 GHz band, and has a choice of 8 channels. No doubt though, the higher band will get more congested in time.

Thanks for posting this. I'd wanted to do the same but with an Ha Solarscope and have been fossicking around for the right unit.
I know Gigahertz from Goat-food so this is very useful.:thumbsup:

Our wireless phone is on the 5.8GHz band. I wonder if it will interfere with anyone's 802.11n? At present everything in the house is 802.11g.
