Very nice, how is it powered up ? I might get one ...what do they mean "Tuned Freq/?" like you enter a freq. in that range that you want it tuned to? I would be interested in the 150-174 one...N connectors...73,s Marcy
12 VDC power. And they factory tune it to your target frequency range - I had them tune mine for railroad frequencies (160 - 161 MHz).
With an IP3 of 40dBm the 1dB compression is probably in the 25dBm range and not bad. It would probably make a good preamp for a repeater as its narrow band at 3-4MHz wide at VHF and would be a little wider at UHF. But for general purpose scanner type use it needs to cover at least a complete band like 136-174 or 108-174 and you could run separate antennas for each band with its own preamp then combine with a triplexer, etc.
A well designed resistive 2-way splitter has about 6dB loss and a home made 5-way is probably 10dB or more loss per port. Why not get a used commercial splitter off fleabay cheap? A non resistive low loss 5-way splitter is going to have at least 7dB loss and there is no way around that.
Slow is ok just made a huge order and want to make sure it processes at some point and the voicemail is full
That item is designed for a closed CATV system with a maximum of 77 carriers at specific input levels and not for an antenna system with hundreds or more carriers at varying levels. It might work in some areas with little RF traffic but it wont work everywhere and certainly not in my neighborhood.I use 4 of these and they work great
I have 20 scanners and 12 Mobile radios using 4 of those connected to 5 antennas on a pole out side with lmr400 to each, and they listening to 1000s of channels and mutable trunk systems with no issues
You are one of the lucky listeners that are not in a high level RF environment. For many people those amplifiers will be a complete failure like they are at my location. They can actually make reception worse with a raised noise floor and ghost signals across the bands created inside the amplifier as Intermodulation distortion due to pushing the poor little amplifier chip inside way beyond what its designed for.
