SWR'ing

Post by **phoebe** » 02 May 2009, 01:16

Next week I take delivery of a Sirio 827 for my home set up. I guess it needs SWR'ing. I have ordered a meter which comes with it.

Rather than put it up on the side of the house and go up and down SWR'ing can I strap the 827 to its pole and then strap it to the washing pole, SWR it and then put it on the house. What I mean is will the readings change, is it OK to do it this way as it will say=ve me lots of tips up the ladders.

Also what channels do I go to to SWR on a expanded SS 3900 as my Channel 33 is channel 19 and so on...
Thanks

Have looked at the booklet on the 827 and the top section has to be exactly 420mm from tip to SWR alan key setting,but good luck with it,as it is an awesome aerial.

Thanks Gareth, Did you find it hard to set up at all?

No Phoebe it is quite easy. A monster of an aerial though, what are you going to mount it on as i would think 2 inch pole is ideal although 1 1/2 might be ok as long as there is not too much wind where you live.

We do have a lot of wind so I have ordered a 2" pole from a local engineer. I hope this will be OK???

I am also mounting on the side of the pole a Sirio discone scanner antenna for my new scanner. This too will take the wind.

I have been very much advised not to use RG58 cable as its crap. Can you recommend a decent cable for both cb and scanner??

Thanks for all the help

rg-213 without going to extreme and costing to much it is one of the best cabls for the money

I agree,i am using RG-213 and cant fault it. It is high spec coax and is more expensive. I ordered 10 metres of it from a U.K supplier (Moonraker) and it came with weather proof seals over the pl plugs.If you are planning to mount on a pole with T+K brackets may be worth buying 2 poles instead of 1 as with the weight of the aerial and the pole on the brackets may be too extreme on the brickwork. I live in a detached property and have the brackets on the brickwork underneath the soffit board/gutter.I have cut one of the poles in half, 10 foot each and have jointed one of them to the other 20 foot pole. The 20 foot pole is in the air and is jointed to the 10 foot one UNDERNEATH the brackets.In theory all the weight is then transferred to the bottom 10 foot pole that is then of course on the ground. Luckily i have a single concrete flags as a pathway in the garden so the pole just stands on the flag and takes the weight.Just a tip for you,hope it helps.

The 827s mounts are designed to fit on 1.5" pole. If you want to use 2" you won't be able to use the original mounting system.

What are the 827 mounts and where would I get 2" fixings from?
