I think I know the answer to this and I could just try it and find out
on my own- but this is easier and funner to ask you guys. ;-) If I were sitting out in my yard in the general vicinity of my Alpha Delta DX sloper and had for sake of discussion my DX398 could I drop my little coil (coupler) over my whip antenna and clip say a 10 ft. lead directly to any part of the sloper? Would I receive the full benefit of the sloper this way? Just thought about that the other day. Curious minds want to know. TIA |

Alpha Delta DX-SWL Sloper Antenna is 'optimized' at the feed-point at 50 Ohms to be connected via a Coax Cable feed-in-line to a Radio/Receiver with a LO-Z {50 Ohm} External Antenna Input. http://www.alphadeltacom.com/pg7.html http://www.rys.nl/Antennes/Alpha%20Delta%20DX-SWL-S.htm http://www.universal-radio.com/catalog/sw_ant/0799.html Connecting the Alpha Delta DX-SWL Sloper Antenna in this manner would result in gaining the Full Benefit from the Antenna to the Radio. http://www.alphadeltacom.com/dxswlii.htm http://www.universal-radio.com/catal...nt/0799om.html Tapping a 10 Foot Wire on to any point of the Alpha Delta DX-SWL Sloper Antenna's 60 Foot Wire Antenna Element 'modifies' the original Wire Antenna Element and your new 'connections' feed-point impedence is unknown. The Coil around the Whip Antenna of the RadioShack DX-398 / Sangean ATS-909 Radio will provide some inductive coupling. http://www.eham.net/reviews/detail/542 http://www.mwcircle.org/res-receiver-sangeanats909.htm http://www.sangean.com/product.php?m...909&prod_id=10 Alternative Hook-Up : The better approach might be to take a 12~15 Feet piece of Insulated Hook-Up Wire and Wrap several 1" Turns around One Foot of the Alpha Delta DX-SWL Sloper Antenna's Wire Antenna Element. Take the other End of the Wire and Clip it to the collapsed Whip Antenna of the DX-398 Radio. Resulting in a longer Whip {Wire} Antenna that is Inductively Coupled to the Larger External Antenna. NOTE - This would basically leave the Alpha Delta DX-SWL Sloper Antenna un-modified for use with the Radio/Receiver it is presently connected to. hope this helps - iane ~ RHF |
