How to use a Flex 6k with Sdrplay rx switching

Although I love my 6400M, sometimes I miss the SDR play for monitoring activity on bands and shortwave listening. So I want to hook that back up, on a separate antenna but have a TR switch to disconnect the sdrplay receive antenna while transmitting on the Flex. It was easy when I used it with my FTDX3000 since i just used the RF output on the Yaesu for the antenna on the sdrplay and it automatically disconnected it during TX. The flex doesn't have the option to feed the full spectrum out to another device. Wish it did.

So I understand I can use a TR switch controlled by on of the rca tx ports. Any recommendations for a simple and affordable TX/RX switch? Or any other ways to reduce the rf into the sdrplay while the im transmitting at legal limit on a different antenna?

    Here is one example relay on Amazon. The relay can be configured as either active high or active low:
