That looks like a good price. I have a story to tell though. The tl;dr is be careful when you move or bend that cable, especially near the ends.
About a year and a half ago I bought two 15M/50 foot LMR-400 cables. One cable was the official MPD-Digital LMR-400 cable, the other sold as Proxicast LMR-400 equivalent for maybe a 40% lower price. Over time and changes, the MPD cable became attached to my UAT-978MHz antenna, and the Proxicast attached to the ADS-B 1090MHz antenna which was not how I had it originally. Well, about 10 days ago, a week after some recent RPI to CM4 changes, I noticed my 1090MHz signal strength and range was slowly decreasing each day.
My test/backup station is offline, so I have spare parts for everything except the 15 meter antenna cable. To troubleshoot this decreasing signal, I one by one swapped out components from my station, including, changing from POE to power adapter, CM4 back to RPI4, Airspy R2 to Mini, one LNA to the other, swapped pigtails, swapped lightning arresters, all the way up to finally swapping the antenna. Nothing fixed the problem. The funny thing was, almost every time I made a change the signal would reduce slightly more. I was probably down to 50% of range and messages. I lost my year-long first place status in the nearby FA rankings.
You can guess what this week of troubleshooting resulted in finding… the cheaper Proxicast LMR-400 copycat cable partially failed from ever so slight bending in 10 cm location adjustments recently. It would get worse each time I touched it. Once I narrowed it down to that with certainty, I didn’t feel like lowering my 30+ foot antenna mast again to move the good cable to my 1090MHz antenna. (I ordered a new MPD replacement cable after doing my best to check and fix the Proxicast cable connectors and stuff). Meanwhile while waiting for the new cable, I just connected my Airspy/1090MHz LNA/receiver to the MPD cable connected to the 978MHz antenna which brings 1090 MHz signal strength back to near normal, but with a 978 MHz antenna, messages are down maybe 10% and avg max range suffers by about 10 nmi. On the bad cable with the FA 1090MHz antenna, my UAT performance is way down but still kinda half-working.
My new MPD cable should arrive late tomorrow if all goes well! Just be gentle with the discount LMR-400 cable and it will probably serve you well!
