Works Best With Counterpoise Kit

First of all Alpha has great service. I ordered the antenna on Thursday, and received it the following Wednesday. I was able to set it up on Saturday, and it goes together quickly as advertised. I wanted to compare it with my existing vertical, a Butternut HF6V with 15 radials. I ran receive signal comparison tests with the HF6V on 10, 15, 20, 40, and 75 Meters. Receive signals were the same on 10M, and about a S unit down on the rest of the bands compared to the HF6V. I then attached the counterpoise kit, and reran the comparison tests. With the counterpoise kit attached The Alpha Vertical signals were either the same or very close in strength to the HF6V.

I then took the counterpoise kit off and checked the SWR with a MFJ-259B analyzer. The Alpha match keep the SWR below 2 to 1 until I got below about 5Mhz. The match on 75M was 3.5 to 1 which is close to the expected match that Alpha publishes. I was using 55 feet of RG8U which could account for some difference in my results.

So far I’m very happy with the antenna, and would recommend it especially using the Counterpoise kit.
