[Antennaware] Baluns for use with 450 ohm ladder line and antenna tuners

[Dave, K2DP]

Am considering using a balun to convert the 450 ohm ladder line feed on my 160-30 mtr inverted V antenna to coax to just get the feed line into the shack. It appears that both DX-Engineering and Array Solutions make products specifically for this purpose, allowing you to use a short length of coax from the balun to the "in shack" antenna tuner. In other words, I would mount this balun on the outside of the house at the point where the ladder line enters the shack, then use RG-213 or equivalent coax to run from the balun to the tuner at the station (15 feet or less).

Here's the question:  DX-Engineering recommends using a 1:1 Balun, PN DXE-BAL050-H10-AT.  On the other hand, Array Solutions recommends their 4:1 balun, AS-200-T. 

Has anyone used either of these baluns in this application and what success have you had with them ?

Thanks and 73,
