Hills Diplexer Part No: Fc609846

[dodgy]

hello is this band 4 & 5 diplexer got power pass that sends power to 2 seperate boosters with one power supply because i want the seperate vhf and uhf antennas to have their own boosters.

heres the information

Brand: Hills

Part NO: FC609846

Type: Diplexer

Output: LO: 45-582MHZ, HI: 610-820MHZ

the reason for this question is because the people use them in mt gambier wire them after the boosters not before them and i was wondering about having a seperate vhf and uhf booster and wire this in after the 2 boosters to send power from 1 power supply to both the boosters in kadina, moonta and wallaroo.

thanks

No, that Hills model does not have power pass.

There are Kingray and Fracarro diplexers with separate power pass.

If you intend to use amps, why not use a single masthead amp with separate UHF/VHF inputs.

This will provide the diplexer and amp all in one unit.

what types and brands of diplexers have power pass on both the vhf and uhf ports

[mtv]

As per my previous post, both Kingray and Fracarro have a range of diplexers that have power pass to both VHF and UHF. Also as I mentioned, it would be easier (and less expensive) to use a single UHF/VHF amplifier which has a built-in diplexer. As they have independent level controls, it's the same as having two separate amps in the one box.

Your first post is a little confusing, as you asked about band 4/5 diplexers, then said you wanted to combine VHF and UHF (band 4/5 are UHF only)

The Hills FC609846 diplexer actually covers Bands 1, 2, 3 and 4 (channels 0 - 35) on one input and Band 5 (channels 40 - 69) on the other input, with no power pass on either input.

thanks for your time,

if i go to do the seperate amps anyway can i just use a power pass splitter backwards

No, a splitter in reverse will not provide a band-split for diplexing and power pass is usually only on one port.

[dodgy]

there are special splitters avaliable with power pass on all ports are they ok for diplexing seperate boosters

NO

dodgy,

Are you related to tyrewarmer20 by any chance?

[beeblebrox]

Col,

As I read down this thread I was wondering the same thing........

[mtv]

It's not just this thread...

Have a look at dodgy's other posts... asking the same questions as tyrewarmer20.. same area.. same antennas.. same amps.. same grammar and punctuation etc etc

Amazing coincidence?

Dodgy /tyrewarmer20

Unless your VHF and UHF antennas are seperated by many meters then there is no advantage using separate boosters.MTV's suggestion to use a booster with separate UHF.VHF inputs still stands.

Th splitters you refer to that have power pass on all inputs have a diode on each power pass that as we all know allows current to flow in one direction only.In this case from all outlets to the input.

If you use it as a combiner,IE back to front then the diodes will be reverse biased and will not conduct.

You could pull it apart and reverse all the diodes and it would then feed DC out all outlets (inlets in your case)

But it is not a diplexer

Not to mention the trolling...
