Default Two antenna questions

1) Does anyone have any experience with or recommend an alternative to an
Alpha Delta switch, model Delta 4? Since the Daiwa CS-401 is discontinued
and seemingly impossible to find, I'm looking to upgrade from 2 to four
positions (more radios) but don't want the cheap junk of MFJ. Is there
another good but reasonably priced 4-port switch that anyone has experience
with, or do you recommend the Alpha Delta? That one is $75. This is for
receive only.


Try the radio swap groups or amateur news groups.

2) What do you do if you have succesfully matched your longwire to a 50ohm
coax with a MLB and have coax coming into the house, but now want to use
that on a high-impedance antenna input (those radios that don't have a coax
connection but just a terminal or jack for a long wire)? Do you do another
MLB with just a short length of wire on the antenna side for connection to
the radio?


This post may not be much help but that said using another MLB in
reverse from low to high impedance is at least theoretically correct.

Practically though you might be better off using a single insulated wire
from the long wire to the radio high impedance input as long as house
local noise is not an issue.
