MTH800 antennas are designed to work on 360MHz to 430Mhz how do they perform on 434Mhz?

M0JGX did some tests using a VNA, these were only "quick and dirty" and no way scientific as the connector on MTH antennas isn't standard.

He used a quality Icom 70cm handheld antenna as a control and also tested a couple of  70cm antennas from China.  The VSWR on 434.000MHz is as follows.

Icom 70cm 1.22:1
MTH800 110mm  1.68:1
MTH800 80mm 1.87:1
MTH800 55mm 2.09:1
Stubby 70cm Antenna with SMA       2.82:1
Stock antenna for DMR / FM dual band radio (SMA)    2.12:1



We along with our colleagues from the Norfolk Repeater Group successfully found the source of the transmission that had kept GB3NB open for 22hours.

It WAS NOT malicious and we feel it best to leave it to the Norfolk Repeater Group to make a statement.

It did, however, highlight great teamwork and cooperation between both repeater groups.


Thanks to the team on the ground

GB7BE is back on-air having received some love.   

We repaired dry joint, tuned the cavity duplexer, turned up to licensed power and added a 5volt regulator for the PI / DVRPTR

GB7EB is back on-air after the antenna and feeder upgrades.

GB7BEs antenna and feeders have also been upgraded but the repeater remains off-air pending a well earned service. It should be back on air next week.


A big thanks to the team for the hard work.
