I wrote to Yaesu today and they replied with the following answer "The ATAS-120 can be used in a fixed base usage situation for 40 meters through 70 centimeters. You will need the add-on base kit (ATBK-100) for 6 meters and up and you will also need to make sure that you have a good RF ground.'

@hamradiotube Год назад

Oh very cool, that is quite helpful. Thanks for doing the research.

@TheDutchGuyOnYT 9 месяцев назад

What would be a good rf ground on a roof like here? So the atbk-100 would not be enough?

@briank3940 Год назад

I love that your neighbors are nice enough to let you use their trees. Pretty cool. Wish there were trees that tall out here in west Texas. Requires masts out this way.

The ARRL EFHW kit was my first antenna. I used it for POTA several times, It has held up well so far. and I enjoyed building it. At the time it was the only EFHW I could find in stock.

@danielzdanowicz6899 Год назад

The ATAS-120A can be used with other non Yaesu rigs if you have the MFJ-1825 ATAS Controller. It it is essentially a bias T that feeds the correct dc voltage on he coax to the ATAS to drive it up and down.

@danimac3953 Год назад

Mike, The ATAS-120A, 120 and 100 can be used with non-Yaesu transceivers IF you interface it with a MFJ-1925 Bias T ATAS Controller. As with any feed line using a bias t caution has to be taken when using a balun choke for common mode currents. Car must be taken to assure that there is no DC short to ground otherwise the bias T could be damaged. Ferrite beads are a better choice for common mode current suppression. 73’s.

As for remote SAR or fairly remote but set comms I use a WILL BERT pneumatic mast. It’s only about 35 feet but as set up in the vehicle it’s relatively easy to deploy and drop. It’s not designed for portable field work but as a mobile command setup. We can also attach a set of military fiberglass masts to it to increase the height for various long wire deployments with a homemade adapter. As for my total man portable ops I still use one of the original carbon fiber masts built by Walter Spieth, DK9SQ, that I bought at Dayton many years ago. Still going strong but built like a tank.

@norrinradd8952 Год назад

I've had the best luck with my EFHWs up in the air just like Mike's. Parallel to the ground and as high as you can get it. I've also had really good results using it like a vertical, again with the feed point a few meters off the ground. I personally haven't had much luck with other configurations that have the feed point on the ground. I'm just guessing that the ground is acting like a signal sponge. A sloper or vertical that starts at the ground works really well on receive though. Good questions, thanks for sharing good answers.

Jackite for a mast. I have two and they are great and a lot cheaper then the dxcommander and others. Always in stock.

@phillipzx3754 3 месяца назад

Yes..I'm late to the party. But when it comes to telescoping masts...I have a 4-element 2-meter/2-element 6-meter quad on top of a 34-foot "Max-Gain Systems" push-up mast. I've bought 2 different mast setups from them. If you need something with a bit more "beef," than the DX Commander or Spiderbeam offerings, they're a good way to go. But I came for the ATAS info. So back to the video. 🙂

@kd5you1 Год назад

I have the 40' / 12 meter Spiderbeam mast and it's built really solid. I typically zip tie a 2/70 roll up J pole at the top with RG8X coax, and then I zip tie an LDG 1:1 current balun at about 34' & run a linked inverted V for 40, 30 and 20 meters... can do 80 with extensions. The Inverted V uses RG8X coax as well, and as long as I zip tie the coax every couple of sections in the upper half of the mast, it works very well. There is a Winlink gateway KD7UHR that uses a DX Commander Classic, and when I am able to connect to it, that gateway works great with that antenna. 73 KD5YOU

@hamradiotube Год назад

That's a heck of a setup! I like it.

@kd5you1 Год назад

@@hamradiotube Thanks! I just noticed that Spiderbeam has their 40' masts in stock again. \o/

@albing1397 Год назад

The EFHW uses the coax feedline as part of the radiator. It would seem optimal to raise the balun/feedpoint up on the top of a 33 ft mast, with a common mode choke 33 ft away (i.e. at the base of the mast).

@hamradiotube Год назад

Indeed it does. You'd be surprised by the multitude of ways the EFHW can be deployed while remaining very efficient. I typically run a sloper with the feed point low to the ground, but I have one that recommends from the manufacturer to put the feed point up high. In practice, I've not seen any real difference in the way they are deployed.

@forgetyourlife Год назад

Sure would be nice to have a definitive answer on that. Same with the choke point. We have multiple antenna makers all stating different “correct” deployments b

@walterkeen5913 Год назад

Atas control information is plentiful but on a high level, apply 12v in one polarity or the opposite to raise or lower it. Be sure to look up details before attempting

@Subgunman Год назад

The secret is 12 volts and 8 volts. DO NOT USE REVERSE POLARITY!!! You will damage the antennas control board within the antenna. One voltage will raise the antenna while the other will lower it. Remember this antenna was designed for use in vehicles and the Yaesu radios as well which are ALL negative ground. You can also damage your radio by trying the reverse voltage trick. Voltages are fed up through the feed line. RF is capacitivly coupled to the antenna while the RF is decoupled through the use of a choke coil for the DC component. A quick and easy fix is to buy the MFJ adapter for this antenna. It will also work on the older ATAS100.

@StuM0OVG Год назад

I have both the 12m Spiderbeam and a 12m DX Commander and both are great but I have to say the 12m DX Commander does seem to be slightly better.

Really? That’s good to hear. I actually have a 12 meter DXC but it was shipped to a friends house as she bought one too. I still need to go pick it up.

@keithslater4868 Год назад

Hi Mike, Another great video! I watched your first video on the Yaesu ATAS Screwdriver antenna and was convinced to try one on my F150 truck. You might already know that it has an aluminum body and grounding etc is challenging! Anyway, I installed it over the weekend and it works great. 5/9 contacts on 10m and 20m to Ohio/Florida/New York and even Madeira. You were absolutely correct, it's easy to install, tune and use with my little FT-891. Is there anything similar made for Icom radios do you know?? Keep the videos coming! 73' - Keith V31ZA

@N4TNA Год назад

The MFJ-1925 is an external controller for using the ATAS-120A with other manufacturers radios. However, I would recommend the Little Tarheel for use on other non Yeasu radios. It will do 80 meters where the ATAS only goes down to 40 meters. If you have to use a controller, that defeats the whole point of the ATAS and the Little Tarheel is a better built antenna.

@hamradiotube Год назад

HA! Noise is an understatement. I've had the power company out here a few times doing some RFI hunting and changing out an insulator. They fixed it for a while until they ran some more wire out here and totally broke everything again. Good thing I'm mostly a portable operator. Fortunately FT8 gets passed the noise so I can still play radio at home.

The coax feed line is not the same as the metal car body. If one attached it to the edge of a metal roof, then it would work as well as on a car but hoisting it up the pole without any ground plane I would expect problems.
