What would the proper connection to monitor sig gen w/freq counter now just using a bnc tee connector on output
is there a proper matching network to make

Dennis,
A cheapie method would be a cable TV signal splitter, but remember it has finite loss. In addition, you'll probably need an adapter of some sort from the type "F" connectors to the generator/counter ports and whatever you will use on test port.

thankyou very much
Guess what I want is to send 455 kc rf to freq counter but not the modulated 100 c tone the freq counter gets 2 signals but only want carrier no audio
going to test a capacitor to block it

Unfortunately there is a problem with monitoring RF signal generators; the output level from the generator has to be fairly high for most frequency counters. This high level is not good for aligning radios for many reasons; for one, it causes the AVC to limit gain.
On some signal generators it is possible to tap on to the signal before the attenuator stage and send this to the counter (this might also lower the output level)

I suppose using a potentiometer to attenuate the signal after the junction might not work.

What I do is use an all-wave digital receiver to check my signal generator. For IF frequencies I use the long wave band of the radio. I tune the radio to the frequency I want and then adjust the signal generator to that frequency. I then reduce generator output and fine tune the generator. For frequencies in the short wave band it becomes somewhat difficult to tell actual frequencies from harmonics, but I usually do fairly well.

You could also do this with your frequency counter--use it to adjust the signal generator, and then disconnect the signal generator from the counter and connect it to the radio being aligned. ...Somewhat tedious, but effective. The frequency counter might also help you differentiate between base frequency and harmonics.

Also, regarding filtering out the modulation tone, this might be difficult, as it may mix with the radio frequency, so removing with a low value capacitor might not be effective, as it may be present as a side band. The frequency is low enough, however, not to cause much error. 455,000 + 100 is nothing, really. This is even less of an error at higher frequencies. When I adjust my signal generator with my digital all-wave receiver, I leave the tone present. I believe that the tone from my signal generator is a much higher frequency, perhaps several thousand cycles, but isn't something to worry about.

You didn't say what kind of generator you have.

Most lower priced generators modulate the oscillator, in which case separating RF from the modulation is not practical. However, if your generator has a separate oscillator and modulated output or intermediate stage, then you can pickoff the RF before the modulated stage.
