Review: Cheap, effective, good build quality. - Perfectly acceptable for my local use needs. From a pizza pan mount, pushing a 20w radio, I’m getting into a repeater 71 miles away from inside my home. VSWR is 1.7:1 from the frequencies I use
Review: Affordable antenna that performs well. - Used this to connect to a Quansheng handheld. I used it to reach a local repeater with the antenna sitting on a table on my porch and was able to hit a 2 m repeater about 6 miles away. I had tried a number of other whip antennas on the unit and the report back was the signal was strong however the mic volume was still low. It is the radio and not the antenna. Bonus I was able to pick up a linked repeater on 70 cm that was 50 miles away. This will end up on my car however it performed well even without a ground plane. The adapter is a bonus as eventually I will use this with a regular mobile unit. The price point is excellent and proves you can get in ham radio without breaking the bank.

### ⭐⭐⭐⭐⭐ nice antenna kit
*by T***E on February 3, 2016*

This is a key component of my poor man's mobile. I'm posting this same review for all the other accessories of the build, but not for the radio which I love and reviewed separately. Here's the build: BaoFeng BF-F8HP Nagoya UT-308UV 22-Inch Magnetic Mount VHF/UHF Antenna SMA-Female for AnyTone, BaoFeng, and Yaesu BaoFeng BL-5 12V Battery Eliminator for BF-F8HP and UV-5R Radios Baofeng BF-S112 Two Way Radio Speaker Regarding each part. Love the radio. The antenna is good and comes nicely packaged with all the needed parts. What is really nice is that the antenna, base, and feed lines are all separate pieces. Mix and match however you want. The base magnet is strong. The antenna and feed lines work well. The long feed line is about 10' which is plenty for me. The 12V adapter is also OK. It's a tight fit, but does fit. It's also pretty cheap - so modify it as you will to change connectors, move the input line, etc. Personally, I think feeding the wire gets in the way because it enters at the bottom of the radio. Such is life. Maybe I'll modify this thing to use a dedicated circuit instead of a cigarette lighter socket - and put on a longer power cord while I'm at it. The speaker thing. -hate- This thing almost kills the build. The first time I contacted someone they reported weak audio. I pulled the hand set and spoke directly into the radio and my audio improved. Also, the wire coil is too short and stiff. Wayyyy to short and stiff. You end up pulling the radio around by the wire. You might as well just hold the radio. But.... It turns out that wrapping the power cord of the 12V adapter and the antenna feed line is an OK solution. Anyways, this was a fun experiment but in the end it seems better to just use a handheld as a handheld and to get a real mobile for the car. Regardless, five stars for being a nice antenna kit
