Two Phased Wellbrook ALA1530LNP Loops = 9 dB RDF 27 dB F/B

Two Wellbrook ALA1530LNP loops phased at 215 degrees with the NCC-2

The front to back is awesome, and I can hear it when I turn these and tune either a local 10 watt TIS station or a high power AM BCB in San Diego, about 440 miles away

Two phased Wellbrook ALA1530LNP loops using the DX Engineering NCC-2 is a true winner. One is 3 feet off the ground:

and the other up 13′:

It seems like having it up higher is better, but I don’t really think it matters much, actually. Here are both – phased through the NCC-2 at 215 degrees:

The reasons I have my two loops at different heights:

  1. One is down slope from the other – and is up 13′ and above the roof of the house so it will be away from the house
  2. One is next to a creek away from the house and 3′ off the ground
  3. The two are separated by 50′ so they show different “time of arrival” signals
  4. They are both 70′ away from the TX Inverted L, which is VERY important
  5. They are both as far away from neighbors houses

These barely fit in my odd shaped lot that has very little space for antennas. I have had other RX antennas like the K9AY Loops that were way too close to the house, and they worked for a while and then became swamped with noise.

As I said, by accident, the DX Engineering DV-40-P was my best 160M RX antenna, but this new (expensive) NCC-2 plus two Wellbrook ALA1530LNP solution reigns supreme. It is VERY much better than anything I’ve had before.

It is also the most RX antenna I can put up here that barely meets the space requirements.

At 9 dB RDF, here is what it compares to a small beverage or a 4 square of K9AY Loops:
