5:1 CUBE™ Unun – Model CU-5-1500 (50:250 Ohm, 1.8-61 MHz, 1.5KW PEP)
Application. For traveling wave, end fed or portable 20-31 foot vertical antennas the 5:1 unun makes a good transformer for converting 50 ohm coax to a 250 ohm feed point. If you use the antenna on multiple bands, the feed point impedance may not always be 250 ohms and use of the unun at high (>350 ohms) or low (<100 ohms) will require reduced power input or the unun may have its power ratings exceeded and damage to the unun may occur. The (5:1 conversion ratio will change for loads other than 250 ohms unbalanced.
Typical application:

HF Loop Antenna Wire Kits (160-10 meters)Product DetailsBrand: Palomar Engineers, Inc.Model: LWK-NNN, NNN = bandFrequency Band(s): 160-10 metersType: Horizontal or vertical loopFull Wave Loop Antenna Wire Kit for vertical or horizontal loops (square, rectangle or delta shaped) from 160 meters to 10 meter. Includes end insulators, #14 Insulated stranded copper wire and spade lugs for attachment to an optional balun
Insulators are a very stealthy, strong, 4 PVC, 2 1/4" long. 1" wide. 1 1/8" hole separation wire antenna insulators and may be black, gray or white depending upon inventory.
Typical size id 1005/F(MHz) and cut for lowest frequency in band segment.
For multi-band capability use 4:1 balun such as our Bullet-4BEB-500/1500 or CB-4-1500EB/5000EB with a feed line choke below it or best bet is to use the Hybird 4:1 + 1:1 balun, CB-4-1-1500. For single band use a 2:1 balun such as a Bullet-2B-500/1500 or CB-2-1500/5000EB. with a feed line choke below it or the hybrid CB-2-1-1500EB with built in 2:1 and 1:1 balun.
