Hello everyone,
I just recently acquired a Texas star dx500v amp and I have some questions regarding hooking it up properly. I have a good understanding of a basic setup using one antenna. but I run two antennas, 1 5/8 wave vertical and a 4 element yagi .

What it perplexing to me is how do I get everything hooked up and running correctly.

Here is what I have on hand now
My hf radio
An MFJ 75 amp power supply
Texas star dx500v amp
Daiwa cn 901 swr and power meter
Daiwa 2 position coax switch
New jumpers all RG 8X or I can use my LMR 400 UF jumpers if need be.

I just ordered a coax “T” maybe I should get 2 ?

I did a little research online and it says that I should also use an antenna switch something to do with matching the output to both antennas? Never heard of such an animal. I know and have a coax switch. Hmm . Anyway if some of you amp experts could give this old guy some pointers, tips , advice and a little help that would be greatly appreciated.
Thank you

The amp goes between the radio and watt meter on a jumper. As long as your antenna switch is rated to handle the wattage from the TS500 you should be good. I assume your just running 10 and 11 meter correct?

As far as your antennas I don't know why you would need a coax T. I figured you have the two way switch connected to both and you can switch between the two.

Thanks 9c1driver
Yep I don’t know why I thought that I would need a “T” . Well after you and others pointed it out to me.lol. With this amp yeah just 10m . If I go to the 11m band I just run the yaesu at half throttle , I’ve been talking all over the world with 50w . Well on the yagi anyway. The vertical is a little bit different story the propagation has to be in my favor.

Correct order of connecting equipment (Orientation).......
Dashes represent the coax jumpers between each piece of equipment .....

Transceiver ---- VSWR/Power meter ----- Amplifier --- VSWR/Power meter --- Antenna Tuner (If Used) --- Antenna Switch --- Antenna

The VSWR/Power meter after the amplifier will NOT measure the VSWR between the transceiver and the amplifier.... which is also a crucial measurement to monitor on your station....
Absolutely NO "T's" in the line.....

    Does anyone know if you can replace the 2290 in a galaxy dx 93t twin turbine with a 2sc2879 red dot? If so, what would have to be tuned?
