Depends, if the length of the coaxial on both antenna are the same then the signal will divide in both anteena provided both antenna are the same with respect to each wavelength.
Re: Batery charger problem.
Try to install electrolytic capacitor across relay ( D1 diode ) say with a value of 4.7 to 10 microfarad or try to use another relay as well. :o
Can you pls elaborate more and how it will fare in the real world?
I have much interest in a yagi design and would like to know more in its appliaction and the feed system to use with it.
Location update were done by the BTS with regards to your mobile phone by periodically interrogating it and update the HLR or the VLR in the MSC
With the RTS there is a signalling channel that is responsible for this and I thinks this is what they call LaPd .
Re: JPOLE antenna design
Flatulent, Imean with regards to the design as shown with the arrow product, any details as to how to implement the feed as it seems that the radiator is isulated from the base so could I use the so-239 but how to connect the radiator to it ? ( the quarter radiator as...
Re: JPOLE antenna design
You are right the quarter wave rod is insulated from the base metal so this is diffirent from the other Jpole design . But how about the radiation pattern? will it be omni direction ? And if I want to do it DIY how simple I could implement the feed section I mean by...
pa 23 100w mosfet
For 860 to 890 mhz you can use the transistor MRF1150 with a max rating of 150 watts with input of 25 watts and needs 50 volts and also it has a gain of 7.8 Db.
Re: JPOLE antenna design
The design from the arrow looks simple and sturdy but I'm a bit comfused as to how it will be feed . I did not see connector or wire connector to connect the coaxial ? :(
The advantage of using a coupling capacitor between circuit stages is that you are not constrained with the dc voltage difference between them but of course it introduce also loses specially in the higher band of frequency.
