Default Got one!


Visited the local candy store, and hanging from the pegboard was the Arrow antenna package. Somehow, it came home with me. I have it mounted to a camera tripod, and have been able to hit several repeaters I could not get with my Diamond SRH940 antenna, nor with my roll-up J-pole. This is going to be fun!

Well constructed for such a lightweight antenna. Due care must be taken, of course, but it seems quite durable.

P.S.: Mole, have you seen this video by K7AGE?

I don't want to fall into a Yagi-vs-log antenna debate, but am curious what factors were important to you that swayed you to the Arrow design (which, by the way, I really like).

...Tom
For what it's worth, I went with the elk 5L dualband they both seem pretty much the same. but i made a telescoping PVC mast for mine along with a tee section to hold the coax out when in vertical mode. Most of the time it is is horiz. with a cushcraft AR-270 on top. It's great for camping trips or hotel rooms. I (XYL) made my bag for the ants. from the leg of an old pair of jeans with a the draw cord in the hem of the leg the other end sewn up.

It's not that I'm intentionally hard on it, but things get stacked, then jostled around, and sooner or later something gets broken. I really wasn't crazy about the PVC shaft on the Elk antenna - that looked to me like something I would end up repairing too often. Those fears may be slightly misfounded, but I'm just passing on my own personal experiences. Since they're both basically the same price, I decided to go with the one that looked like would last longer for me.
Mole,
Very nice job on this whole presentation. I had the same concerns, the only reason for the pipe was to allow the vert./horz. thing with just a 1/4 twist on the same mast. In the 4 yrs. iv'e had it it's been fine even when left out during snow storms at camp, which is where it see's most of it's use. They are both very good American made products and will serve us well.

For the benefit of anyone that stumbles across this thread, here is a "how-to" video on how to work the satellites with your HT. I used the Arrow antenna in the demonstration:

I've never used an Elk log periodic, but they be ugly... The Arrow, with my trusty FT-60 do make a cool pair! I'm thinking of putting one of those LNK Receiver Pre-amps inline to boost the UHF. Anybody got comments? ~Steve

I built the Ramsey 440Mhz Pre-Amp kit for mine. It works great. It's VERY inexpensive too!

Here's the link to the build:

If you decide to do this, take a few pics of your work and share

Question

Last week I ordered the Arrow II 146/437-10WBP handheld 2 meter/440 Mhz yagi antenna directly from Arrow Antennas. I also ordered the roll up storage bag with the pockets that is made in the U.S.A. The price for the antenna is $139 and the bag is $40.

This antenna is specifically designed to allow you to work the satellites using an HT, following the satellite through the sky with the antenna in your hand. At first I was a little hesitant to spend that much money on an antenna that could be home-brewed for quite a bit less, but I decided to purchase it because of the ease in which it disassembles, breaks down, and stores away in a small sized package. When you camp in an RV or Jeep, you learn to appreciate products that take up very little storage space.

I was very pleased that I received the antenna very quickly only a few days later. Here is a pic of the antenna taken out of the bag and laid out on the table:



The boom on this model is split with a piece of copper tubing pressed into place and riveted. The copper is a very nice tight fit that ensures that the boom is sturdy when assembled.



Here is the boom assembled. The overall length of the boom is 37.5"



There are no sharp edges on the antenna. All of the edges are rounded and the holes for the elements are deburred



This model also contains a 10 watt 2m/440 duplexer that fits in the handle. You can remove it if you like, by pulling the plastic end cap off. The foam handle goes over the top of the coax that runs up to each driven element.



The gamma matches come pre-assembled and tuned for you, although it can be adjusted if desired. This thing is literally "assemble and play". Here is a pic of the 440 Mhz gamma match:



Notice how all of the square edges on the aluminum block of the gamma match are rounded and polished and fit on the round element is perfect. The workmanship on this little antenna is really top quality:



The boom and all of the elements are made of very light weight aluminum. Each of the elements has the female threaded end pressed into the rod. Here is a pic where you can see one of the press marks on the end:



And the female threaded end insert:



Here is the anenna partially assembled with all of the 2 meter elements:



Here is a close up of the antenna fully assembled with all 7 440Mhz elements and the 3 2 meter elements.



All of the 440 elements come screwed together in the package. This is helpful for the first time you assemble it, becase several are very close in length. Anyone with a basic understanding of how a yagi is built can put this together without even looking at the instructions, although the instructions are well diagrammed if you need the help.

Here is a view looking down the center of the antenna. Note the size and spacing of all of the 440Mhz elements.



Here is a view of the antenna in the hand looking down the center at both sections. You can see how clean the installation is when fully assembled:



Arrow's advertising repeatedly mentions how lightweight the antenna is. Well, here's proof: Even a kid can hold it up:



Here is the antenna fully disassembled and stored back in the bag. When storing, it's especially helpful to keep the elements that go to gether stored together. By doing this, I was able to fully assemble the antenna in about 10 minutes while taking my time (and sipping on a beer ).



The foam handle on this antenna is removable; it simply slides off the end. This will allow you to use this antenna as a portable base if you so desire with the addition of a square U bolt attached to a small mast on a tripod. Another nice thing about this antenna is that the company has a complete parts list with pricing in case you need to replace any of them. One thing to remember is that you might need a BNC/SMA adapter if your HT uses an SMA antenna. Arrow also sells these if you don't already have one.

I did a quick check with the MFJ-259B analyzer on 2 meters while holding the antenna in my hand (since that is the intended use case scenario). It showed under 2.0:1 SWR bandwidth from 140.5Mhz to 148.93Mhz. The best SWR was 1.2:1 at 146.12 with R=43, X=6. Since my analyzer won't go to 400Mhz, I could only use a basic SWR meter to test that part of the antenna. It showed that the SWR was under 2.0:1 for the entire 440Mhz Amateur band. That is certainly to be expected with elements of this diameter.

Yesterday I used the antenna and made my first HT, handheld antenna satellite contacts with it as A0-51 went over head! Wow, that was fun and challenging! I can tell that I am going to have a blast doing this. I can't wait to try a few other birds and even the ISS.

Overall I'm very impressed and pleased with the quality and design of this antenna. Yes, it is a little pricey, but the convenience of it breaking down coupled with the quality design is worth it to me. Arrow offers a 90 day no questions asked refund if you want to return it for any reason. These are the quality types of Amateur Radio products that I really like to see on the market.




Look's great, gotta few questions and would rather post here than make new thread or email mole so...
Couple Questions here....

1: according to your post Gains are: 4.6 dBd on 2m and 10.3 dBd gain on 440 Mhz.
So with 5w in on 2m;
Effective Radiated Power (ERP) = 11.5897 dBW = 14.42016 Watts
Effective Isotropic Radiated Power (EIRP) = 13.73 dBW = 23.64906 Watts

And with 5w in on 70cm;
Effective Radiated Power (ERP) = 17.2897 dBW = 53.57596 Watts
Effective Isotropic Radiated Power (EIRP) = 19.43 dBW = 87.86458 Watts

Right? Of course many things to consider...

Has anyone thought about removing the "Purple" paint and polishing the elements?

Last: why only 150w PEP? if you remove the duplexer and run RG8 mini and ran 350w... would the antenna melt!?

I seriously doubt if that antenna would melt, but I wouldn't want to be holding it.
