UPDATE on 10/6:
Once again, sorry for the delayed update. Terry is still having issues from his fall, and is seeing various doctors and doing various tests. That, coupled with material delays from our suppliers has us backed up again; although, we are completing orders as quickly as we can. 
You, our customers, are very important to us and your patience with our situation is, and has been, very much appreciated.

UPDATE on 5/17:
Terry was in surgery for over 7 hours today. The shattered vertebrae had penetrated the nerves in his spine (every piece had to be extracted one by one) and he was leaking spinal fluid. Your well-wishes, thoughts and prayers are much appreciated.

Saturday evening while working on the 2m array for our new shop, Terry fell 18 feet from the roof to the rocky ground. He sustained a shattered L1 vertebrae and a fractured sternum, along with other  injuries. He’s having surgery on Monday (5/17) to repair the L1 vertebrae, but the doctors are telling him he may be incapacitated for possibly 12 weeks.
We are hoping to find some help in the production of our antennas so we can get them out for the contest, but we are making no promises at this time.
We apologize for the inconvenience and if you want to cancel your order, we will return any money paid via PayPal.
Thank you for your understanding.

Due to the overwhelming increase in 10GHz activity, our supply of dishes, mounts and feeds have been depleted. After getting quotes from our suppliers, we were shocked to find they have all increased their prices based on the rising costs of aluminum, copper and steel.
Therefore, unfortunately, we have been forced to raise our prices accordingly.
Please note, the prices for our complete systems now includes the mount.
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 2021, 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.
Terry Price – W8ZN

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.
