Sirio boomerang

[Rm24uk]

Hi forums

I live in a block of flats 10 floors up and grabbed hold of a balcony antenna the boomerang
I have mounted it on an old sky bracket it currently stands quite close to the balcony above
I would say half a metre and all I am picking up on my 3900 is 9 pounds of static on virtually
Every channel the swr seems ok but can't understand why the performance is so poor anyone
Got any suggestions??

interference from an electrical item in one of the flats or you flat would seem to be the problem i would think sorry to be the bearer of bad news

Had the same deal when i used a modulator on the balcony i am however going to try moving it further out see if that makes any difference

thanks for the reply

sounds like a old tv set or like stampman says somthing very nr bye

When i look in the distance i see lots of big radio masts but to be honest they cant be the problem or i would have picked this skip up when i had it in my car, is it possible my power supply could be causing this???

[stampman]

if its a std power supply built for cb or radio then i would doubt it a plasma tv can cause probems or even a bt hub power supply has been known to do it as well

I do not have a plasma tv but i do have a sky broadband hub will turn it off or the wireless see if that makes any difference, also me power pack is very old and does buzz alot

i get 9 pound of noise from nextdoor ....when they go out its gone (plasma) tv

the problem is with broadband hubs is that they run on 3650–3700 MHz band & they do interfere with CB radio frequency`s also here is something else i have found what can interfere with cb frequency's Certain high power cordless telephones operating on frequencies below 853 MHz can cause interference to other radio users also which transmit in the frequency band 470-854 MHz.

so basically not looking good for CB radio users who have Neighbours who have wireless networks or have a wireless network hub in there own home & cordless phones

Buy yaself a few ferrite plugs to put on ya cables also it wouldn't hurt making an air choke
5-6 winds of coax around a 4 and a quarter inch diameter near the antenna base (if you cant find anything to wind it around just use a 2l plastic bottle that's close enough)
just do a google search for air choke or ugly balun
