RVs DxPedition Camping Restricted HOAs Apartments- Boat House Townhouse Emergency- Penthouse. (COMBO)HIGH POWER Multi band Magnetic Loop Antenna 10-60 Mts + 33 Ft of Low Loss Coaxial wire BR-240. This antenna is easily convertible: Active loop up or down with a simple 38 inch 3/4 PVC pipe.
The antenna is light, portable, serviceable, handles a reasonable amount of power, characteristic Q rejects some interference, and is capable of detecting some weak signals. The High power magnetic loop handles 100W PEP easily. All Stainless Steel Bolts , Nuts and Washers INCLUDED!
Had the chance to try the antenna on Saturday. Attempted to make 30 contacts into pile-ups for contests. 100 watts and I made contact with every one on the first attempt.
All contacts were less than 1000 miles but all were 59's. I put the antenna to use on my regular 40 meter net this morning and was able to hear and work a net controller that I have not been able to hear previously. So it's obviously doing its job. Out Standing Quality and Price is Well Worth the Mag Loop. VARIABLE CAPACITOR: Translucent enclosure, fully.Assembled ready to use High voltage air core variable capacitor. Stainless steel bolts, nuts and washers. RADIANT LOOP: Qty (1) carefully coiled 38" Diameter 5/8 copper Radiant loop 3. ACTIVE LOOP: Qty (1) 7"Diameter 3/4 wide Aluminum plate 4. Qty (33) Ft Low Loss Coaxial wire BR-240 with (2) Gold plated ¼ inch post connector and Qty (1) PL-259 Connector. PVC Frame: PVC frame with Qty (10) 3/4 PVC T joint and Aprox. 14 Ft of 3/4 PVC pipe cut in several segments. Qty (10) 6 inch electrical nylon ties. Instructions: Assembly and use instructions. We reserve the right to make any modification to improve the design.
User Assumes all responsibility for use of this antenna and fitness of purpose. YOU MUST USE AN AUTOMATIC ANTENNA TUNER NOT INCLUDED! Currently with 100W PEP , rain or shine, I make contact with HAMS across the USA and other countries in South America and Europe. TUNING PROCESS The process of tuning the antenna for Dx is straight forward and is as follows. Turn OFF the auto-tuner and choose the desired frequency on the Transceiver.Turn on the volume on the transceiver and turn over the capacitor on the antenna and find the spot where maximum noise is heard. Turn on the auto tuner and proceed to auto tune the antenna. This process usually results in a 1:1 swr or very close to it. After this tuning process, when you search for other stations to Dx, you do not need to perform auto tune until you are ready to transmit on a chosen frequency.
Once the frequency is chosen, you press auto tune and get your SWR down to 1:1 or very close to it. If the auto tune does not tune satisfactorily after a frequency change, go back to No.

For example, you may want to change the diameter of the radiant loop or the diameter of the tube forming the loop. Or the material of the radiant loop.
Or double up a large loop for operation on 160 Mts. Also you can also play with the plane of the loop, vertical or by relocating some portions of the PVC, lay it on a table and have a horizontal polarization.
Or maybe you would like to compare the propagation differences between active loop up or down. Which can be made by adding a pvc coupling and a pipe extension to the top to provide support for the newly reconfigured radiant loop. This antenna type, finds a very interesting application as a ready portable antenna, easy to use and store, requires no counterpoise or radials, and allows HF in areas where users are constricted by a number of reasons.NOT that there is anything wrong with those, but the discreet profile of the Magnetic Loop has its charm and applications.
