Interference from transmitters to telephones almost always requires installing an RFI filter at the phone receiving the interference to correct the problem. At VHF frequencies grounding the transmitter has little effect on RF and is mostly for lightning. Filters at the transmitter only reduce ...

No, it's not possible to get a "matching" amplifier to the one you already have. The key here is all of the components have to be exactly the same. Most importantly are the matching power output transistors. All transistors with the same part numbers are not the same. Their gains and several other ...

Hello Stylz,

I just wanted to give you some technical input since it seems InterTech did not understand your question. The RF splitter and combiner are exactly what you use to add a pair of equal power amplifiers together. The splitter divides the output from the exciter in to a pair of 50 ohm half ...

I think one of the simplest solutions would be to hang a quad loop in the front of each car stall. The vertically polarized full wave loop exhibits bi-directional characteristics that radiate on the front and back side of the loop but has deep nulls on either side. It's basically a 10 foot loop of ...

You can extend coax and get good results but there are a few things to consider. First, is the coax of sufficient quality to even bother. For example I would not waste my time adding another 50 feet of RG-58U since the cable has high loss to begin with. Second is you must choose a good quality ...

This would not be a project for a beginner since it would require mounting a transistor with a different case style and pin out. With this in mind if you can mount the 2SC2539 to the heat sink and wire it in with the shortest, low inductance wire possible..... the 2SC2539 is an ideal high power ...

It should be noted that upon further investigation it was found that this customers 300 watt power amplifier was only mounted on the small aluminum heat spreader supplied with the board and not properly mounted on a suitable heat sink. This combined with tampering of R2 (the bias setting) almost ...
