Shark Antennas S-F5S 5-Pack (10, 15, 20, 40, 75M) Mono Band Mobile Vertical Antennas with 3/8x24 Threads, Handles 250W Max

I paired these antennas with a mfj tri-mag mount to operate my ft-891 from my truck doing pota activations where I don't have time to setup a larger antenna. These have actually surprised me in how well they work. So far I have used the 20 and 40m sticks and have made over 250qsos in 2 activations mostly on 40m. The 40m stick gives me 1.5:1 swr in a narrow window so I have it tuned so I can operate from 7.2-7.5 under 2:1. It's acceptable and I have no trouble getting out and making contacts. I would recommend bringing a nano vna or some sort of ananalyzer with you to set these up as it makes it much faster and easier

So far I’ve used these for a number of POTA activations. Mainly the ones for 20 and 15 meters. The 20 meter one is dialed is at 1:1 SWR and haven’t had to touch it since I initially adjusted it, and I’ve made a lot of contacts with it. The 10 and 15 meter ones are about the same, but have only used them a couple times. The 40 meter one is finicky to tune, but has worked okay. Have yet to try the 80 meter stick. I have enjoyed using these antennas when it’s raining and I operate from inside the car. Mostly run QRP CW and FT8.

I have yet to hook these up and run the VNA on them to check them out. Nor have I hooked them up to my radio. But, initial assembly had my 15 and 40 meter whips unable to screw into the base coils. I chased both the internal and external threads with a 3/8-24 tap and die to clean up the threads. It appears, probable, the plating built them up too much and created an interference fit. That shouldn't occur, manufacturing tolerances were off. The other three fit up just fine.

These are the basic hamsticks. Quality so so. I had to use a tap and die set to fix the threads on two of them. Otherwise, fine sticks.

It was in first rate condition, appears all stingers tuned to mid-band. instructions were simple and complete It was an "Open box" but it was all there.. and the shipper: Giga Parts. Assembled and slapped on the roof look good on the MFJ analyzer.... Not on air yet though. Got 'em on the air. Only problems were stupid user (Wrong port selected on radio.. Duh) Seriously impressed with performance.. Wish I'd gone this route long time ago.

These antennas tunes up easy, well built, and work well.

I had my doubts, but let me tell you, They work great I've worked amazing DX off these antennas with only 100 watts no amp. Quality construction and center loaded, and long enough to get signal in the hear even the weak stations.

Tuning was easy, didn't need to cut the 40m whip. Deducted half a star because the original package was opened, but functionality not impacted.
