Many Amateur Radio operators are discovering the advantages of dedicated receive-only antennas. RX-only antennas usually offer better signal-to-noise ratios than transmit antennas. RX only antennas may also offer special capabilities like phasing, for noise reduction and/or directionality.

DX Engineering RTR-1A Receive Antenna Interfaces DXE-RTR-1AYou don’t need a high-level transceiver to utilize receive-only antenna systems. Devices like DX Engineering RTR-1A antenna interfaces add receive-only capabilities to any transceiver. Entry-level transceivers from any manufacturer of HF equipment can now benefit from a dedicated receive antenna.

Receive-only systems include Beverage types, magnetic loops, short verticals, phased arrays, indoor and outdoor active antennas, receive four squares and many others. In fact, many vastly different receive-only antenna systems are available from numerous manufacturers. For the home-brewer, the possibilities are only limited by your imagination.

Yaesu Day 2016 is over. Thank you to the hundreds of you who walked through our doors today. What a great turnout! The feedback we heard was very positive, but we’d love to hear your thoughts. Comment below, or on our social media accounts. 

We’ll keep you posted on our next Open Box retail sale and additional events. For those who couldn’t make it, we look forward to seeing you at Hamvention in a few months!

Thanks, everyone!

12:07

We’ve now given away six gift certificates – the last of which was for $100. Many more folks have joined us today, and coaxial cable is flying off the shelves. 

10:30

About 100 Hams are currently in the store, chatting with one another and meandering through the incredible deals available at Yaesu Day. They come from all backgrounds. Two traveled from Niagara Falls, a father-son duo came in from the Warren, Ohio area (about a 50-minute drive), and several young Hams are ogling the awesome equipment.

10:03

The first two winners of the Yaesu gift certificate drawing have been anounced. We’re giving away a $50 gift certificate every 30 minutes, and a $100 gift certificate at noon!


9:20am

Dozens of people have poured into Summit Racing’s retail superstore for Yaesu Day, and the aisles are getting very crowded!  Attendees are starting to take advantage of the mountains of clearance deals.


8:59am:

The doors have officially opened for Yaesu Day 2016. Yaesu’s Dennis Motschenbacher, K7BV, and Chris Wilson, N0CSW, are both in attendance to talk about Yaesu’s products with attending Hams. DX Engineering is also holding its largest-ever Open Box and Clearance sale during the event.

 

8:38am:

DX Engineering Chief Operating Offer Tim Duffy spots a nearby retail store television playing an automotive video and quickly hijacks it to show the K1N Navassa Island DXpedition DVD. DX Engineering was a major sponsor of the DXpedition, so the video will make an eye-catching background show to the clearance racks it is mounted above.

 

8:32am:

DX Engineering’s Tom Parkinson, KB8UUZ, or “Parky,” as he’s more commonly known, works his way through the aisles, making sure to take pictures and video of the beautiful Ham Radio display. Parky is very involved in PCARS (Portage County Amateur Radio Service), K8BF, and is looking forward to meeting other club members at Yaesu Day.

 

8:25am:

The first Hams walk through the door for Yaesu Day. They don jackets and hats with their call signs custom embroidered. They meander through the mammoth Summit Racing Equipment retail store to the back wall, where there are several thousand square feet of tables and racks sporting new and open-box Ham Radio equipment.

 

8:20am:

DX Engineering’s employees are here, displays are set up, and Yaesu Day is about to get under way. The doors don’t officially open until 9am, but DXE’s hams, loaded with coffee and outfitted in their finest DX Engineering apparel, are itching to make some eyeball QSOs.


Your SWR (standing wave ratio) meter looks at forward (used) power and reflected (wasted) power as a measure of antenna system efficiency. This basic measurement has been used for decades to indicate “good” versus “bad” antenna operation, but it is actually an indication of the match between the radio and the feedline at a given frequency. The SWR match changes with frequency.

Daiwa CN-801 Professional Series Bench MetersIn order to use your SWR meter correctly, you must use a continuous (unchanging) signal. That’s the reason you cannot measure SWR with your transmitter in the SSB (single sideband) mode. SSB power only exists with modulation present and varies in response to the applied audio amplitude. To perform SWR measurements, it is necessary to use a mode that has a constant carrier, such as AM, FM or CW. Each of those modes provides a continuous, steady output that allows SWR measurement.

Set your meter to the appropriate power setting for your transmitter. Then set your meter to the “Forward Power” setting. Adjust the meter sensitivity control to the maximum value on the forward scale. After adjustment, switch the meter to “Reflected Power.” You may now read your SWR on the reflected power scale. NOTE: A “cross needle” type meter reads SWR and forward and reflected power simultaneously.

An SWR of 2:1 is actually acceptable. This represents that about 89 percent of your power is being accepted by the antenna system. A very good 1.5:1 SWR means that about 96 percent of your signal is being accepted by the antenna system. Anything below 1.5:1 is an excellent SWR value. Most modern transceivers start to “roll back” their output power automatically with SWR values just below 2:1. This is done to protect their RF output stage from damage. This means that your 100 watt output transmitter may only allow 30 watts maximum output (or less!) on an antenna system with a 2.5:1 SWR.

No two Amateur Radio stations are the same, so buying an “off the shelf” coaxial cable assembly usually means dealing with several feet of extra, unwanted cable. Not only does that clutter up your Ham shack, sending your signal through excess coax cable also has a negative affect on station performance. DX Engineering has just introduced a Custom Cable Builder that allows you to build a precise cable assembly tailored to your unique setup. You select the cable type, its length, and the connectors you want.

Custom Cable Builder

In addition to improved performance and a cleaner shack, the Custom Cable Builder will save you money, since you’re only buying the exact length of cable you need to complete your coax runs. You can also use this tool to build custom copper braid (strap) assemblies to create a one-off grounding system. Using the Custom Cable Builder is a no-cost service; you only pay for the cable and connectors used to make your new cable.

Here’s how it works:

1) Select the DX Engineering cable you want to use. This includes RG-231, RG-8X, RG-8U, 400MAX, RG-6 or copper ground braid. During this step, you’ll also enter the length of your new cable.

2) Choose the connectors you want on each end, e.g. PL-259, BNC, Type N or Type F, in both male and female configurations. You may also select one or both ends to terminate without a connector. Depending on the cable type you select, mix and matching connectors is OK too. For example, you can have a PL-259 on one end and a Type N connector on the other. If you’re building a ground braid strap, then your connector choices will consist of standard ring terminals (lugs) in #10, 3/8″ or 1/4″ sizes.

3) Once you’ve got your specs filled out, click “Add to Cart” and you’re done. DX Engineering’s techs will then build your custom cable assemblies. Each new cable endures rigorous hi-pot testing before it leaves the DX Engineering facility. In most cases, you’ll get your custom cable assemblies in just a few days.

Rule 1: Coaxial connectors are not pipes. RF connector gender is determined by center pin, NOT by their threads.

Coaxial cable connectors have specific designations and their gender is determined by the center pin. In Amateur Radio, the PL-259 is the most popular coaxial cable connector for HF and low VHF antenna systems. The PL-259 is also known as “UHF male” in most of the world, and is an “M male” connector in Japan. It mates to the SO-239, also called UHF female. You can tell them apart because the PL-259 is the male PLug that mates with the jack or female SOcket, the SO-239 connector on equipment and antennas.

The PL-259 and SO-239 are great RF power connectors for HF systems. However, for constant impedance and lower loss, Type-N is the coaxial connector used for VHF and UHF transmitting systems, with N male typically mounted on the cable, which mates to the N female on equipment and antennas. Test equipment, metering and receiver cables often use BNC connectors. Very low power and small devices, including hand-held transceivers, use a connector called SMA. Very high power HF, VHF and UHF commercial systems use exceptional low-loss connectors called 7-16 DIN, which are now used in high-end Amateur gear. Satellite and cable TV and HF receive antenna systems use F connectors, also called Type-F. Typically, F male compression connectors installed on RG-6 type cables have a center conductor that is the center pin and the F female connectors on equipment and antennas have a center receptacle. There are many other connectors in the world of RF… too many to mention here.

Rule 2: Never ask for a cable with “end” connectors.

Knowing about Type-N connectors, you can imagine the confusion that is caused when someone refers to a cable assembly having an “end” connector.

“Was that ‘N connector’ or ‘end connector’? What kind of ‘end connector’ do you need?”

The bottom line is cable assemblies aren’t made with “end” connectors. For RF interconnections between pieces of equipment and to antennas, most coaxial cable assemblies are terminated with either PL-259 connectors or Type-N male connectors.

Be sure you know exactly which connectors you need when referring to coaxial cable assemblies. Use proper connector designations and remember that their gender is determined by the center pin.
