works ok, but subject to water problems Time Owned: 0 to 3 months.
I purchased this antenna as a WARC band supplement to my Hustler 5BTV antenna which has performed very well on 80-40-20-15-10 meters. It was installed on a separate 6 foot long galvanized mounting pole, 4 feet of which was concreted in the ground, mirroring the mounting arrangement of my 5BTV. A DX Engineering ground radial plate was also installed, again mirroring my 5BTV installation.

The WiMo GP-3W is a simple ground plane antenna, split aluminum tubing, fastened together with stainless steel hose clamps, and one trap (for the 30 meter band).

I installed it using the measurements provided in the 2 page instruction manual, under dry conditions, and it initially presented an SWR of less that 2:1 on all three WARC bands.

After the first rain, the SWR was way over 3:1 on all bands. This antenna is not in any way resistant to water intrusion. By comparison, my Hustler 5BTV barely shows any change in SWR regardless of wet or dry conditions.

I suspected the culprit was the single trap in the GP-3W, so I drilled a couple of weep holes in the bottom of the trap and water poured out. After a couple of days of drying, the SWR is almost back to where it was when I first installed it.

Gentlemen, make your own judgements.
