Hi, I wanted to congratulate you for the superb DL 2el antenna 11mt that I have assembled with satisfaction.
SWR ok from 26.500 MHz to 30.00 MHz, center band as indicated 27.500 MHz.
Excellent yield and reception. Thanks so much.

Hi,

look your 2 element delta loop installed two months ago on 2” diameter pole without any issues. We had strong winds in the past few weeks but the antenna responded in a very excellent way. I have also a vertical antenna and could make a lot of comparisons between the two antennas. The delta loop is much more silent than the vertical either in good and bad weather conditions, so I could receive a lot of weak signals wich on vertical were completely absent. Forward signals on the delta loop are all from a minimum of 4 S-points higher than the vertical. Thank you!

Best regards,

G.F.

Delta Loop 2 el. SmarTech




he SmarTech 27DL2 is the Delta Loop that, most of all, responds to the needs of those looking for a small, lightweight and high performing system.

It is a low noise antenna since is free from electrostatic noise. Thanks to its excellent signal to noise ratio, the 27DL2 is perfectly efficient even when other types of antennas are practically unusable.

The antenna can also be mounted on a lightweight support (pole/rotor) and reaches its characteristic performances from small heights from the soil.

Radiation patterns clearly show that the 27DL2 is suitable for both long distance DX and medium/short range contests. For details see the antenna patterns.

A SmarTech 27DL2 has gain, take off angles and boom-length/performances ratio better or similar than a 3 el. Yagi.

This antenna has a flat SWR curve covering 27 MHz at less than 1.5:1 SWR




SmarTech Deltaloop Antennas are designed to reach the best possible configuration of Forward Gain, F/B Ratio, F/S Ratio and Radiation Solid Clearence becouse of design resulting combinations are not affected by the 50 ohm native impedance constraint.
Therefore once the best antenna configuration is reached, a specific gamma match system provides the perfect 50 ohm impedance for the maximum power transfer and for the maximum system efficiency.

MATERIALS

The antenna main structure is made of aluminum alloy EN AW-6060/82 UNI 9006/1 (Anticorodal 60/100), which provides excellent long-term durability against the most severe weather (ice, water, UV rays, fine particles, acid rain), and better resistance to heavy wind load.

The Delta Loop is supplied with stainless steel parts AISI 304 (Inox Austenitic UNI / EN 10088) and steel S235JR2 (UNI 100 series), certified according to 2000/53 / CE + RoHs standards.

Insulators are made of Polypropylene PPC 5660, resistant to remarkable thermic excursions (certified for temperatures from -20°C to +130°C), with high load at break (ultimate tensile strength 25Mpa), excellent abrasion-resistant and volume resistivity > 1018

The horizontal wire is one of the most important components of the antenna. Here flows the highest current and RF radiation is maximum. Therefore the quality of the material most determines the system efficiency.


Delta Loop 2 el. - SmarTech


For this, SMARTECH has focused its utmost care and efforts for the production of a specific, special wire consisting of 99.99% pure copper with antioxidation coating and insulated with a special polymer.

The wire is also used for military and aerospace applications because of its excellent dielectric properties (insulation better than glass), abrasion and tear resistant, UV rays resistant, chemical solvent attack resistant. IDT 8 kV. Operating temperatures -65+150°C.


An high efficiency Gamma Match adapts to 50 ohm the 27DL3 (relative dielectric constant εr=2.0 @1 MHz - best dielectric properties than fiberglass and polyethylene, dielectric strength 600kV). Power rating up to 5 kW (optional).


SmarTech Gamma Match



The antenna is made to obtain the maximum electrical efficiency, the best mechanical resistance and durability, thanks to its high quality materials. It is also suitable for installation in mountain areas and coastal (corrosive) areas.

SmarTech antennas are designed with the minimum necessary electrical/mechanical joints. So, parasitic resistances are the lowest possible so as to minimize unwanted RF dissipations.

In order to maintain its best performances, each Delta Loop is individually checked before shipment.


Costs include proper packaging, completion of customs documentation and shipping tracking 24/7. All products are shipped with the most important and reliable international couriers.
