The Q is not all that sharp and between the coil and the extendable element I can tune to no more than 2:1 and down to almost 1:1 on 40m and 20m. Haven't tried higher than 20m so far. I spred the ground lines equidistant around the base. Enjoying so far.

This is a great antenna for portable operations. It tunes fairly well (1.3-1.5 SWR) , its easy to install and to carry. Definitely recommend

Very quick delivery....... EASY to set-up . Tuning very close to the manual description, minor adjustment depending on surroundings. Used a Nano VNA analyser the first time and follow those recorded settings , 1.2 SWR all bands. Very satisfied Limited portable outings Logbook shows over 12 DX countries into EUROPE with less than 17 watts on 20 meters. Looking forward to better band condition ........... ENJOY

Took this on a mini dxpedition to Costa Rica TI7/VE3BW. easy set up made qso's around the world on 40-10 meters. Good SWR when correct tap selected. Over 1000 QSO's with 75 watts max. Well built, .definitely recommend.

I used the Alpha Antenna Jaw and clamped the antenna to a medal picnic table here at the Burnaby Radio Saturday coffee get together. I used it with my Xiegu G 90 and Icom 7100 all from battery. JS8Call and voice. I've loaned this portable out to other hams and they love it ability to pack it in pack. The metric if I remember is M10 x 16. I use a bolt to screw into the antenna.

This is a great quality Antenna made from good quality materials. Comes with a carry case and radials, tuning coil and extension rods. Works very well on 40, 20, 17, 15 and 10 meters. I transmit and receive signals from Laval which is North of Montreal to Florida, Puerto Rico, France, England, Slovania etc, all on 20 Watts. I highly recommend this antenna which can be mounted within 10 minutes and this supplier!!!

An update on my previous review .. the threading used on all of the antenna components, including the ground spike is not imperial, it is metric. I have confirmed that it is M10-1.5, thus making it incompatible with the 3/8-24 treading used on most Amateur and CB antennas. I had great luck with this antenna operating portable over the summer of 2021. - VE3WMB

Excellent vendor, prompt and very professionnal. I highly recommed! The antenna is well built and should last a long time given a modicum of care. Putting it together is very easy and assembly is rapid. I used it with 10 quarter wave radials -- two each for the following bands: 40, 20, 17, 12, and 10 meters. I achieved very low SWR on 40, 30, 20, 17, 15, 12, 11, and 10 meters without any difficulty. HOWEVER, you need to reduce the antenna length for 15, 12, 11, and 10 meters. On these four bands, matching could not be achieved with the coil attached. However, excellent match was obtained by removing the coil and retracting some of the upper whip sections, as required. The antenna then works like a telescopic whip on top of the four mast sections. The antenna is perfectly usable without a tuner of any sort. This said, an analyzer or a nanoVNA greatly facilitates setup. So far, I am extremely pleased with the product ...
