6m 4elements Yagi antenna 6m4DX3 for portable or stationary use
Prepare yourself for a new sunspot cycle 25 with 4element 50 MHz Yagi. Enjoy the rising popularity and exciting contacts on the 6meter “Magic” band. 4 el. antenna can be used as portable or stationary. The antenna combines its strong 30 x 30 mm boom with a strong “Goliath” bracket which will make sure the antenna is always solid. Elements are tapered to reduce vibrations at high winds. Starting element diameter is 12 mm, and the middle part is 10 mm and 8 mm ends. Tapered elements will reduce the wind load.
What 6m4DX3 mean?
6m – Magic band antenna
4 – Elements
DX – Intended for use in DX part of band 50-50.5MHz with excellent SWR
3 – 3m boom with extremely strong construction.
The antenna is pre-tuned, so there is no need to move, cut or use a rasp file for any element to get perfect SWR on the intended frequency range. As all our antennas are, this Ham Radio antenna has been designed with professional full-3D EM modeling software. The antenna is calculated with the influence of boom, balun, and connector… Once the antenna is up in the air, you should expect solid SWR across the whole designed range, true gain, and F/B as given in the table.
Four Elements on 6-meter band are situated on the antenna boom of just 2.92 meters long. Since this Ham Radio antenna has 4 elements it is very easy to set up. Up to 20 minutes is enough for assembling even if you see the antenna for the first time. Everything is labeled, just put number to number. The antenna can be assembled with cheap hand tools, as well as with power tools.
For DX hunters, it is good for the E-sporadic season since when there is an opening you don’t need long antennas. The antenna has the best gain for its boom size, and excellent F/B.
Everything is included in the antenna box: Antenna, balun with connector, and bracket. Yours is just to assemble and have fun!
The default maximum power input is 1000 W. Optional up to 8000 W.

Read the short review about the 6m4DX3 PA50-4-3B antenna from eHam.net:
This antenna is excellent!
Easy to assemble, easy to dismantle. You can work mobile or work from home. It always performs well.
First of all Antennas Amplifiers company does not deliver your antenna if previously they do not fully test it, check all parts, and measure all values. They do not leave customers without answers. This is important!
Often I even listen on a 40m band with this antenna and hear so well and with minimum noise almost like it is FM. The side rejection is excellent.
The gain and F/B ratio is as advertised.
Assembling is easy and fast. Every element is marked; instructions are clear; materials and plastics are all of very good quality. You can not go wrong dealing with this company. The owner is a friendly fellow who responds on all your questions fast and accurately.
Antennas Amplifiers generally made excellent products for more than 30 years. I have two of their beams and both working as advertised.
