I am using the xtronic coupler and a 20 db fixed attenuator on my 200D .24 radio.
If I should upgrade to a 7000DLE, would the fixed attenuator the same?
Thanks,

Don,

This topic is what you need to read:

However, the TLDR version is, assuming you are only running the 100W, then that's 50dBm out, less the 44dB coupling factor, so +6dBm peak out of the coupler. That's well below the safety limit of +13dBm, so no attenuator is required at all for either radio. +6dBm is also close to the optimum value for maximum signal-to-internal crosstalk level. Dump the attenuator for either radio.
