13el Single Connector Dual Band 6m 4m Antenna 5070dx13
Highest class common connector 6m and 4m Dual-Band antenna. Spare your free space on the tower for another antenna. Two antennas on a single boom behave as two mono-band antennas.
Single Connector Dual Band 6m 4m Antenna 5070dx13 on 7m boom 13 elements will produce booming signals with 59+ reports on both bands 6m and 4m. Devoted to contesting and DX hunting.
Antennas-Amplifiers Product Benefits. A Major advance in Amateur Radio antenna design.
- F/B and G/T superiority.
All antennas have been calculated using state-of-the-art full 3D Electromagnetic Simulation Software including the influence of the boom, bracket, baluns, and connectors. The performance of antennas designed using these techniques is exceptional, far better than antennas designed using “wire” programs.
- No tuning antennas
Before dispatch, we assemble each antenna and test antenna characteristics. That means you may expect exceptionally good electrical and mechanical characteristics including low SWR across the designed range immediately after assembling.
No need to move the dipole, cut, or tune any element to get perfect SWR on the intended frequency range. Everything is pre-tuned.
That lead also to another very important detail. When assembled and tested each antenna is complete with all washers, nuts, bolts guy rope supports, etc.
When packing all parts are already on the antenna without the possibility to “forget” important parts to put in the box. So you will always receive a complete antenna that we tested just before dispatching.
- Designs that work well in all weather conditions
- Low SWR and superior G/T, F/B, and F/S ratios across the entire bands
- Excellent mechanical properties
- High durability, built without compromise
Why all the above is very important? Why we do not use free wire programs like EZNEC (Pro), 4NEC2, MMANA-GAL, or AO? Like all other producers or simulators do?
EZNEC, 4nec2, or AO producers or simulators put on the web pages excellent “simulated” antenna patterns produced by wire programs. Looks good on a computer screen. But what about reality?
Elements are not infinitesimally thin.
Boom size is not 0 (zero) mm.
Boom corrections programs exist. But what about accuracy?
Electrical terminals from balun coaxial cable to dipole are probably at least 10 mm long which is not “simulated” 0 (zero) mm. It will lead to worsen SWR or when tuned to good SWR to sharp antenna resonance.
Real antennas are not in free space. They are surrounded by metal parts not calculated in any form by wire programs.
Errors made by amateurish programs like EZNEC (Pro), 4NEC2, MMANA-GAL, AO, etc. only for the above examples are unacceptable these days. They will lead to wrong antenna gain, especially F/B. At least 5-15 dB lower than predicted. That means if the antenna is “calculated” for F/B 30 dB it could be anywhere between 15 dB to 25 dB. Unfortunately, that also means the antenna will have much worse G/T which will lead to bad contest results and poor EME reception.
This has nothing to do with the obtained SWR of 1: 1 on the antenna. SWR 1:1 is not related in any circumstances to antenna gain, F/B, or G/T.
