Part II : Beyond the Simple One-Wire Outdoor Shortwave Antenna http://groups.yahoo.com/group/Shortw.../message/14406 OK so you have your Eton E1 Radio and you want more out of it. Clearly besides a new Radio the only major way of doing this is a better Shortwave Antenna for the Radio. Assume you live in an Urban Area and AM/MW Radio Stations become a problem when you start using an External "Longwire" Antenna with your Radio. Assume that you have the Space for an External Antenna and that there are No Restrictions on Outside Antennas. Now lets start with your eton E1 Radio : It uses a PAL Jack for the external Shortwave Antenna connection. So first of all you need a PAL Plug to mate-up with the PAL Jack on the Radio. -Note- The PAL Connections are the EU {World Wide} equilvalent of the USA's "F" Connector. and most of them work well with TV type 75 Ohm Coax Cable. -OR- You could use a PAL to "F" Adaptor. So why not use TV type 75 Ohm Coax Cable as your Shortwave Antennas feed-in-line ! Converting from the Coax Cable to the Wire Antenna Element(s). To 'match' the Coax Cable to the Wire Antenna you will need a Matching Transformer. The simplist an most common to find is the 300 Ohm to 75 Ohm TV type Matching Transformer. -Note- The TV type Matching Transformer greatly attenuates the RF Signals below 5 MHz so to some extent it is an AM/MW Band Rejection Filter. The Two 300 Ohm Wire Leads of the Matching Transformer give you a few Shortwave Antenna Options : * Dipole or Inverted "V' or Multi-Dipole Antenna * Windom Antenna * Horizontal Wire Antenna {Longwire / Random Wire} * Inverted "L" Antenna The Dipole and the Windom both use each of the Two 300 Ohm Wire Leads like a Balun. And you can either Cut them to a Shortwave Band Size -or- Cut them to fill the Available Space you have to work in Safely. Examples of Cut-To-Size Dipole Antenna Sizes : 60m = 95.4 Feet Tip-to-Tip or = 47.7 Feet per Arm 49m = 77.0 Feet Tip-to-Tip or = 38.5 Feet per Arm 41m = 63.7 Feet Tip-to-Tip or = 31.8 Feet per Arm 31m = 49.0 Feet Tip-to-Tip or = 24.5 Feet per Arm 25m = 39.3 Feet Tip-to-Tip or = 19.7 Feet per Arm 22m = 34.1 Feet Tip-to-Tip or = 17.7 Feet per Arm Examples of Cut-To-Size Windom Antenna Sizes : 60m & 41m = Long Arm 47.7 Feet and 31.8 Feet Short Arm 49m & 31m = Long Arm 38.5 Feet and 24.5 Feet Short Arm 31m & 22m = Long Arm 24.5 Feet and 17.7 Feet Short Arm -Note- The Dipole and Windom Antennas are 'balanced' Antennas and a Ground may not be needed to make them function well. The Horizontal Wire and Inverted "L" Antennas are single Wire Antennas and you will use one of the 300 Ohm Lead to connect to the Wire Antenna Element and . . . What Do I Do with the 'other' Lead ? ? ? Connect a short 3-4 Inch Bare Wire to this other Lead and use a Hose Clamp to Secure it to the outside of the "F" Connector attached to the 75 Ohm Connector of the Matching Transformer - you now have a Magnetic Longwire Balun (MLB). The Horizontal Wire Antenna can be any Random Length Wire that you can Safely Rig within your Property Limits. The Inverted "L" Antenna can be any Random Length Wire that you can Safely Rig within your Property Limits. -OR- Inverted "L" Antenna can be Cut-to-Size Examples of Cut-To-Size Inverted "L" Antenna Sizes : 31m & 60m = Vert-Leg 24.5 Feet and Horiz-Arm 47.7 Feet 25m & 49m = Vert-leg 19.7 Feet and Horiz-Arm 38.5 Feet 19m & 41m = Vert-Leg 15.1 Feet and Horiz-Arm 31.8 Feet { Relative Aspect Radio 1V : 2H } -Note- The Horizontal Wire and Inverted'L" Antennas are 'un-balanced' Antennas and a Ground will be needed to make them function properly. For the Coax Cable feed-in-line i recommend RG6 Quad Shield Coax Cable. As musch as you need to get from you Eton E1 Radio to your Matching Transformer and Wire Antenna Elements. All of these above Wire Antennas should have lower Noise and better Signal Levels then a simple plain wire Antenna; and provide for a more enjoyable Shortwave Listening (SWL) experience. hope this helps - iane ~ RHF {pomkia} .
