Great little antenna
Put the antenna up and noticed water getting in too the main part of the antenna so put a plastic cap over it works well so farOne year on and working brilliantly with my mod no water ingress and looking like new very pleased 👍👍

Good little antenna
Works well and is very small and doesn’t stand out making it target

My unit was defective
One of the antennae ports on the base of the antenna had a half-complete thread, and could not be used. Could have easily been checked before being made available for sale.

Now I can more accurately track my cat!
We have a petTracer GPS cat tracker collar which sends the position from the collar to the Home Station using 433Mhz signals. The aerial on the Home Station is not very powerful so I often lose the signal when the cat is a few hundred yards away. With this antenna installed on the roof I can now follow him for in excess of ½ mile. This antenna is well made and was easy to install. I had to connect an additional SMA extension cable to the 3m one supplied but that was no problem and there seems no loss of signal because of the long run of cable. I appreciate that this is a very specific use of the antenna but I can highly recommend it. I did smear the threads with Vaseline so that bad weather won't affect it.

Disappointed
Bought this antenna about a year ago and give it a great review... Now am deeply disappointed now as the radials are starting to rust.

Deceiving display on line
Product is fine but pictures and details to present the product on line is not ideal
User
As ordered
Exactly ass ordered though the shipment took some time to arrive.
User
Great gain with easy SWR calibration.
Turns any handheld device into base station quality.Tune as 1/4 wavelength radials with 96% 1/4 wavelength radiator as a good guess. (if required)Note: As much as this antenna helps, VHF/UHF are line-of-sight so HEIGHT is everything - get this antenna as high as possible for best results (light antenna poses very little wind resistance).
