UPDATE – Moving 3456 MHz loop yagis to 3400 MHz
After hearing about the demise of 3456 MHz here in the US, I contacted Dave Olean, K1WHS, who is the previous owner of Directive Systems and had originally worked on the 9cm loopers. He confirmed what we saw, there is a VERY slight degradation in gain moving them down in frequency. Here are the results:
DSE945LY – .5 dB
DSE976LY – .4 dB
DSE9112LY – .2 dB
As my friend Gene, W3ZZ, used to say “the DX will never know the difference!” The percentage of frequency change is so slight that the return loss still should be in the -20dB range which is 1.2:1 or less.
Going forward we will make changes to the loop lengths on any new 9cm loop yagis. We anticipate opening sales again on 9cm loop yagis sometime in late March or early April.

PRICE INCREASE NOTIFICATION
To our valued customers:
We are faced with a situation we don’t like – the cost of materials and shipping have skyrocketed in the last 2 years. Whether it’s related to COVID we aren’t sure, but the reality is our costs have risen and we either have to “turn out the lights” or raise prices.
Our major aluminum mill now takes 9 months to deliver our tubing, this hampers our “just in time” manufacturing process which helps keep our prices down. To make matters worse, several of our main suppliers of aluminum rod used for elements on 2m, 1.35m and 70cm antennas have stopped carrying it and we’ve had to go with more expensive alternatives, with greater shipping costs to us.
FEDEX, UPS and USPS have all gone crazy with price increases, and while we always shop for the least expensive shipping cost when sending antennas to our customers, the fact is when we purchase materials we sometimes have no choice of what carrier they use and how much they charge. Just the cost of a cardboard box we use for shipping antennas has doubled in the last 5 years, even though the process has improved with all the CNC and laser cutting technology employed. We’ve even removed several box sizes so we can order larger quantities of less sizes, which gives us better pricing. Also, we don’t pay extra for fancy printing on our boxes that get tossed once the contents are removed.
The bottom line is we aren’t going anywhere soon. The feedback we receive from you, our customers, tells us we are doing something right and we GREATLY appreciate it! Unfortunately, effective May 1st 2022, we will be raising our prices roughly 10% on most all products. As a user of our antennas for K8GP, and my own roving and new fixed station, I feel your pain as well – but we have no choice. Our pricing is still below other manufacturers and we will continue to provide the best service possible.
Margie (K4MEP) and I thank you for your support.

Does your Power Divider Look Like This?
Some manufacturers charge twice as much, but only guarantee 20dB of Return Loss. Directive Systems guarantees at least 30dB (1.065:1 VSWR) of Return Loss in the most popular portions of the amateur bands.
