*** Covers 40-20-17-12-10 meter ham bands under 2:1 at most heights no tuner required, 80, 15, 6 meter bands require wide range tuner
*** Great digital/FT8 antenna on many bands without tuner
*** Low SWR on many bands or use antenna tuner
*** 500 watts/1.5KW/5KW PEP (SSB-ICAS) options
*** Stainless Steel hardware for long life
*** Halyard Hoist hole for ease of center support installation or hang at ends only
*** Insulated #14 wire for durability
*** High Strength insulators (may be black, white or gray)
*** Ladder Line to 1:1 Balun (Note 1500/5000 Watts CUBE Balun can be mounted to a wall, 500 watts MB-1-500 is supported by ladder line
Super convenient and quick – great for contest operation! Choose 500, 1500 or 5000 watt PEP (use 5KW model for digital modes over 1000 watts).
INSTALLATION
For best results support center at 30+ feet and ends over 15 feet. Angle of feed each side must be great than 45 degrees or 120 – 180 degrees total between each side preferred. Any length of 50 ohm feed line ok (from the matching unit) but longer feed lines over 50 feet may show reduced SWR on some bands due to losses in feed line and soil conductivity, nearby objects, etc. Due to local ground conditions, antenna height and feed line length, SWR may vary from samples shown and an antenna tuner may be required or some bands to bring SWR at end of feed line to acceptable levels.
Antenna Length Note:These antennas are shipped from the factory with each side at 46 feet long (92 feet total) so that you may adjust(shorten) the length for your personal installation.The SWR graph shown for this product is for a side length of 44 feet as this length provides a lower SWR in the 17 meter band than the 46 foot length. The longer 46 foot length tends to shift the SWR curves to the left (lower frequency) which can sometimes be offset by reducing the length of the ladder line (up to 2 feet max). Each antenna installation is unique – try the antenna lengths as received and shorten the wire length by bending back the wires on themselves at the ends as needed.
Use an antenna tuner for 80, 30, 15 meters and reduce power if balun saturation occurs.

TECH NOTE: We also stock RFI kits to protect effected devices such as garage door openers, computers (laptops, desktops), dsl/cable routers, ethernet hubs and many more devices. If you run a high powered RF amplifier in your ham station also consider a linear amp RFI kit which will cut down RFI transmitted by your station. Remember there is always a “transmitter” and a “receiver” of RFI and the quest is to find and choke the “path” the RFI has selected – you need to add ferrites to both the transmitting side and the receiving side to eliminate RFI problems. The RFI-HTS kit only helps suppress RFI on the receiving side.
Typical RFI Problem/Solution:
Hello, I am Larry, a ham operator and I am having interference issues with my Direct TV system. My station is a FT450D through an Ameritron ALS-600. From the amp through a coax switch to choose between an OCF dipole or an Hustler 5BTV vertical. Any power over 100 watts and my DTV goes off the air and must completly reboot/format. Coax is RG-8. The DTV dish is pointed away from the dipole and separated by about 25'. DTV was totally useless! They suggested I not talk on the radio while she is watching TV! Please help me with a reasonable, cost effective soultion. (The wife gets really pissed when I shutdown the tv!) Thank you, Larry
Hi Larry,
Your RFI problem is quite common and is usually a sign of either a radiating coax feed line or reception of your radiated signal (source) by the Direct TV (the victim) through either the AC power lines acting as “antennas” for your ham signal or the coax braid of the satellite antenna acting as an antenna for your signal.
The solutions are straight forward:
1. To make sure your feed line is not radiating you need a feed line choke at each antenna feed point (also makes your antenna work better since it is not using the coax as part of the antenna). You can use our simple Kit 110 with 5 snap on chokes on each antenna for this purpose. Part # Kit 110 at $27.50 each – one for each antenna. These chokes will keep your feed line from radiating and coupling into your ac power lines. INFO HERE
2. The radiation from your antennas themselves may also be getting into the ac power lines and coax braid of the Direct TV antenna so you need to protect the victim receiver. Depending upon the sophistication of your direct TV setup (e.g. home theater, dvd, tape player, sub woofer speakers, etc), the path of the RFI may be coming thru the AC power lines of any connected device to the video including the video monitor itself! To help solve this problem we have a home theater RFI kit for up to 5 devices (you need a minimum of two – one for the Direct TV receiver(AC and coax input) and another for the video monitor AC power lines and HDMI or video input cable. Our kit part # is RFI-HTS. INFO HERE
These items should help reduce the RFI and let you operate on the air while your wife watches TV.
