Roger, It’s not just the VDSL noise but the SMPSU’s as well that give me grief round here. VDSL affected 30m most as I have overhead poles in my back garden so limited option to escape. VDSL cabinet was a street away.
I found the RX loop (Wellbrook) worked poorly near the house and put it outside where it performed much better also with a rotator but agree EW would be my preference if I had to choose a fixed position. I also tried with 2 short terminated beverages each 40m long running along a garden wall EW. They worked ok and complimented the RX loop to give me better coverage. I can’t say they were excellent as comparing in a noise free option was a choose but I used them for a couple of seasons before I changed to remote RX in a field a couple of hundred metres away using a WiFi link where I put out 2 x 200m long beverages in a lot quieter location. It might vary at your QTH but worth trying as putting up a short beverage temporarily to try as it won’t break the bank.
