  1. So with a little bit of sleuthing, I think I may have solved this mystery. It appears that at 6.45am on the morning in question, a lightning strike did occur just NE of Oban. It was very bright and was followed by a large clap of thunder. I deduce that it was a fierce enough lightning strike that it awoke Skipper Billy and the thunder clap that followed, shook his house and blew his bedsocks off.

    A picture tells the story. The yellow dot is the offending strike.

  2. Thanks Ian. Shame they changed the design of the Quad. I would have to dismantle it too, and it would be more awkward to position. I will probably go for the 3 or 4 element Yagi as positioning will be much simpler. I have loads of coax and baluns and have ordered the FCD. I'll order the antenna next week and get it set up.

    Will prob have a few questions about setting up the software when the time comes.

  3. Thanks for the links guys, you can never have too much knowledge and knowledge is the key to understanding.

    No I didn't fall asleep reading that Ian, it all helps.

    I have kind of narrowed it down to a 5 options.

    #1. Build a Yagi in 3 or 4 element.

    As this antenna will be in the loft space which is not huge, size is a consideration too. All these options are affordable and small enough for my purpose.

    But which one??????

    ps. having read your post again Ian, it seems the 4 element Yagi is what you were using and the Quad is what you are now using. opinions on these would be welcome too.

  4. Ok so I have looked at the DIY antenna described in the Sky at Night  article and it looks fairly simple to build. I have also looked at a few other option that are ready made and not very expensive.

    My question is, I have seen a few antenna's which specify different amounts of gain. So how relevant is the gain number when using an antenna for receiving only. Does higher antenna gain make it more sensitive? Give it more range?

  5. Hi Ian, yes I meant the cameras only see across to Northern France.

    That was a useful link and an interesting read. I will have to read it again to digest it, but on first reading it does seem that a 50MHz antenna will be too big for my uses. I don't think it would even fit in my loft. :p

    But still, its all food for thought.

  6. Hi allcart, I thought I'd seen a copy posted on this forum, and I've found it! It's post #20 here

    There's a lot of stuff on this forum, but this thread started by Steve Nickols is a good diving off point. Being fairly well south of the UK you should be able to get good signals. I use a FunCube dongle and my antenna is in the loft, certainly not ideal and I'd like to get it outside, but which presents problems. My background noise levels tend to be a bit on the high side (compared to Steve's), but I capture a good many meteors.

    Good luck



    Thanks for the links.

    Like yourself, I may have to install the antenna in the loft as I don't have a south east view unless I go up onto the ridge of my roof (no chimney either). I already have a 4 camera video meteor detection system on the roof just above gutter height so anything I mount up there will obscure the cameras. I have thought that maybe a turnstile reflector design could work as it would lay flat in the loft space, but have not researched enough to know yet.

    lots to think about.

  7. Continuing on from my other meteor thread.

    I woke up at 4.30am for some unknown reason, so decided to get up for a coffee and check the meteor cams.

    91 meteors on East cam

    82 meteors on West cam

    77 meteors on South cam

    50 meteors on North cam.

    My North cam suffers most from light pollution so captures are generally less than the other 3. That being said, My North cam captured the best meteors of the night. As well as the fireball I mentioned in my other post, I also got these.

    The first is another mag -4.2 Northern Taurid with yet another double terminal flare as it burned up in the atmosphere.

    And finally a Mag -5.4 Draconid. The skies were becoming murky at this point with less stars visible, so the magnitude estimate may not be entirely accurate. None the less, it is still a notable capture.

    Maybe Halloween is a spooky night after all.
