“Oh dear, I was excited when my Alpha Delta DX-EE antenna arrived from DX Engineering. Great, I thought, up it goes. Well, then came the testing. The results clearly show that this antenna does not properly cover 40 meters – only about 20% of it without a wide-range tuner. So it can’t be the station reference antenna. See the details in the video. I’ll keep working on it.”
|Wire Antenna Band||Wire Antenna Frequency|
|40 meters||7.0 MHz|
|20 meters||14.0 MHz|
|15 meters||21.0 MHz|
|10 meters||28.0 MHz|
Alpha Delta Parallel Dipole Antennas consist of the Alpha Delta DELTA-C center insulator and end insulators, ISO-RES coils connected to the 80/40/15 meter wires, and separate wires for 20 and 10 meters.
All wires are assembled to the center insulator and utilize stainless steel hardware and 12-gauge solid copper wire. These antennas are shipped fully assembled, except for threading the 20 and 10 meter wires through the parallel wire element spacers. These are inserted during the antenna final assembly and installation process.
* Model DX-EE covers 40, 20, 15 and 10 meters
* Model DX-CC covers 80, 40, 20, 15 and 10 meters
* Model DX-LBPLUS covers 160, 80, 40, 20, 15 and 10 meters
Overall length for the DX-CC is 82 ft., 100 ft. for the DX-LBPLUS, and the DX-EE is only 40 ft. in length overall. An antenna tuner is required for 15 meter operations on each of these antennas.
