プレシデント電化製品「IOWA」RW CB ラジオアンテナ

Almost no need to tune. 1.3 SWR out of the box.

I did numerous tests with multiple brands of antennas with different lengths, I tested the Hustler HQ-27, Radioddity CBL-561 and the President Iowa, both Hustler and Radioddity antennas were giving a high SWR around 1.7 to 2.8 and were difficult to tune with to the radio, I then installed the President Iowa with the tuning rings preset in the center before installing, I checked the SWR at channels 1, 40 and channel 20 at the center of the spectrum, it was 1.2 at channel 1, dead flat at channels 20 and 40 which I think was fantastic, I could fine tune it to make it dead flat across the whole band but I think it’s good for now and the reception and receive are clear, I believe the length of the President Iowa works very well over the longer antennas but it depends on the location of the antenna, I have installed in a front fender mount with a PL-259 type connector and a SO-239 to 3/8-24 adapter which gives the option to easily install numerous types of antennas, it is well worth it for the price.

Excellent antenna with a very quite noise floor, easily adjusted to a flat SWR. Excellent range as well. Using it with my President Bill II FCC.

Nothing not to like. Great little antenna for the price.

I have had this antenna for 4months and it broke at the plastic base. I had it mounted with a spring and it was sheltered by my cab for about the bottom half of the antenna. I do travel on the highway but usually at 75-80 mph. Well that must be too much. The antenna separated at the bottom by the president clear rubber band. The swr went out from 1.0 across the band to 2.2-2.7. That was the lowest I could get it other than that it was in the 4. Range. I really liked the antenna before it broke. Nice range for size, looks good, easy to tune. Not much bad to say about it except it broke.
