Xtronic XDC-4SO Additional Attenuation
Posted: Thu Feb 02, 2023 1:48 am
I ordered an Xtronic-4SO coupler. The plan is to implement PureSignal on my 7000DLE MKII using an ACOM 1000 amplifier. The published specs for the Xtronic coupler are as follows:
Frequency: 1 - 60 Mhz
Power: 3,000 Watts PEP
Coupling: 44db +/- 1db
Insertion Loss: 0.04db
Return Loss: 30db
Directivity: 35db
At the bottom of the page, there is a note: ** For higher power stations, Additional 10dB and 20dB inline SMA attenuators are available for $10.95 each. - See Accessory Listing Below
How do I calculate if the Xtronic coupler has enough attenuation for this Amplifier? I am guessing that there is a formula, but I have not been able to find it. Xtronic has not answered the phone or replied to my email inquiry and the fellow at Ham Radio Outlet that I talked to said that he didn't know the answer. Unfortunately, Ham Radio Outlet didn't have the optional Xtronic attenuators in stock.
