Anybody got any bright ideas on how to reduce the signal coming out of
the back of the transmitter? We have a one watt transmitter but wish
to reduce it down to approx 300mW so as not to interfere with another
close station. (we are going to be using this TX as a link system)
Would some kind of attenuator do the trick or is there another method?
The cheaper the better.
Heya guys, Anybody got any bright ideas on how to reduce the signal coming out of the back of the transmitter? We have a one watt transmitter but wish to...
Probably the cheapest/way to reduce power is to add attentuation to the aerial lead. Add length to the cable... not sure of exact figures but adding 10 metres...
Geoff's right. The easiest way to reduce power is to use more coax. The data is in the back of the Dick Smith catalog. If I remember correctly the spec for...
Speaking of 2.4GHz spectrum. I just hooked up some 600mW Wi-Fi PCI cards to have a look at the 2.4GHz spectrum in Invercargill. The amount of wireless LANs is...
This is of interest to me, as I need to move my transmitter for a few weeks while decorating the studio. I have a 7 metre coax extension lead. Will this cause...
Hello Grant, Will be a little loss in TX power... now to get my calculator out :))) If your TX is out putting 500mw @ 88.4 MHZ, SWR of 1:1 at 7 meters of coax ...
Hey Johnno, Studying your figures, it seems that RG58A has a loss of 13mW per metre? So would I be right in saying to get a 1 watt TX down to approx. 300mW or...
The figures are based on the Freq Range, SWR ratio (ie: 1:1) and the cable that is being used... If we use 88.4 mhz, 1 Watt, SWR 1:1 and using RG58A = 39...
I've been watching all the suggestions for reducing power and that is a simple and practical way of dealing with it. However if you have the schematic diagram...
Unfortunately it's not as simple as working it out to a mW per meter. That's why things are done in dB. For example, driving a coax cable with a known loss of...
You can make yourself a simple T attenuator with a loss of about 5.2dB Close to that value will suffice as its not exactly critical. Build it in a tin box with...
By the way, it's 500mW eirp, output from the antenna... Cheers Dean Groove 107.7FM PO Box 10 989 Wellington Ph 381 4766 (381GROOVE) Fax 381 4755 Mob 021-457...
That coax cable one is handy but I've just finally noticed the power budget one isn't right. It asks for dBm on a lot of things and provides answers in dB when...
Hey guys, I just realised that I never actually thanked everyone for their ideas on reducing the signal output. Shame on me. So....thanks everyone! We have...
