 FS: Wiltron 62N50 VSWR Bridge  
The bridge had been used only occasionally by myself in conjunction with a Spectrum Analyser & Tracking Generator to make VSWR measurements at single frequencies or a band of frequencies. It has been well cared for and never subjected to RF power levels that could cause damage. It still has a new-like appearance. Connectors are Type-N.
$255 with free shipping in CONUS. Prefer Postal money order or bank check. Personal check OK to ship item after it clears.

 Bird 8201 500 watt Dummy Load  
Bird Dummy Load, 8201, 500 watts, N Female Connector, works as it should. I have used this dummy load from 3.5 - 30Mhz. Works great. I checked the SWR with a Rig Expert analyzer and SWR is flat up to 30Mhz, SWR on my LP-500 shows 1.00 to 1.01 on the HF Bands.
Front "feet" plate is bent a little but does not affect performance.
If you want it checked at a higher Freq, I can borrow a NanoVNA H4 and go higher.
