Directive Systems Antennas. SUPER HIGH QUALITY ANTENNAS.
|
Time owned: 0 to 3 months

I received an antenna today from Dave at Directive Systems for 2304 MHz. Just another example of a perfect antenna from these world class folks. Measured 60 watts froward and 250 MW of reflected power. Everything I have purchased from this company comes the same way. Packed well, quickly shipped, manufactured correctly and fairly priced. What more can you ask?
Thanks Dave,
Terry N8ERM

I bought two 2314LYRM 1296 Mhz loop yagis. These antennas function very well at 1.2 GHz. It's 14 elements on a 36 inch boom, rear mounted, with an N connector feed.
With it's 14 dB gain, it can take a 10 watt signal, and turn it into an EIRP of over 200 watts. Combine that with another 14 dB gain at the receiving end, and it's real easy to make some awesome DX.
Since it's so light, it's easy to go roving. The only consideration is that the loop elements are made of aluminum sheet metal, so they can bend or crush if you're not careful and place a heavy object on the antenna. If you intend to make the antenna permanent, you need to give attention to make the aluminum materials weather-resistant, such as coatings etc.
I suggest you use a solid photo tripod to hold onto the rear mount. You can easily get 10-24 wing nuts at any well stocked hardware store, and use it to mount the antenna in place. Use the tripod to point elevation and azimuth as needed.
Dave was very helpful in interacting over e-mail, getting to know the antenna and any other questions. His contact was superb.
So, if you're using it for portable/roving use, it's a great value for the size, weight and gain.

I purchased a 21 element rear-mounted loop yagi for 2304 MHz from K1WHS of Directive Systems. It's on a 3 foot boom and I ordered it in it's fully assembled configuration which was shipped via UPS in a securely padded tube. It was nice to NOT have to tune the driven element or install the loops!!! This is a great antenna for roving and portable work. The gain and pattern are excellent without any anomalous sidelobes. Plus, K1WHS is a really nice person on the phone. That counts for a lot in my book. In all honesty, I would have purchased an antenna such as this from Mike Staal K6MYC of M2 Antenna Systems in a heartbeat. Naturally, I am very loyal to Mike since I was his technical sales manager at M2 for a few years and he helped me to get on 2 meter moonbounce. However, he CURRENTLY doesn't manufacture an AMATEUR BAND antenna for any frequencies higher than 1296 MHz. Anyway, I'm sure I didn't hurt M2's feelings by buying a K1WHS antenna for 2304 MHZ. I would recommend Directive Systems loop yagis for 2304 MHz and above to anyone! K1WHS is just super.
